This tutorial is an introduction to the histology of the different tissues in the human body and the cells they are made of. Test yourself on our cells and tissue histology quiz at https://khub.me/jnhny Oh, are you struggling with learning anatomy? We created the ★ Ultimate Anatomy Study Guide ★ to help you kick some gluteus maximus in any topic. Completely free. Download yours today: https://khub.me/1fcwd A tissue is a group of cells that has a similar structure and acts together to perform one or more specific functions. In this tutorial, we will introduce you to the 4 main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue and nervous tissue. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules, whereas connective tissue underlies and supports other tissue types. Muscle tissue contracts to initiate movement in the body and nervous tissue transmits and integrates information through the central and peripheral nervous systems. In this video tutorial we will take a closer look at the histology of the main cells and tissues under the microscope. - 0:33 introduction to histology - 1:22 epithelial tissue histology and types - 5:45 function of the basement membrane - 6:20 connective tissue histology and structure - 10:53 muscle tissue and types of muscle cells - 13:11 basics of the nervous system Want to test your knowledge on the cells and tissues of the human body?

The science of cells that never get old | Elizabeth Blackburn
 
18:47
What makes our bodies age ... our skin wrinkle, our hair turn white, our immune systems weaken? Biologist Elizabeth Blackburn shares a Nobel Prize for her work finding out the answer, with the discovery of telomerase: an enzyme that replenishes the caps at the end of chromosomes, which break down when cells divide. Learn more about Blackburn's groundbreaking research -- including how we might have more control over aging than we think.

Information and the origin of life - Did cells write their own software?
 
00:59
What is something computers and humans have in common which constantly needs upgrading in computers but not in humans? The answer is software. You might not have realized that you have software but inside the nucleus of each of your cells a program is written in the form of three billion DNA letters. Intelligent programmers write computer software but what about living things? Evolutionists tell us that the information in the first living cell just appeared by itself, with no intelligent input required. But is that possible? The answer is a resounding no. Even one of Australia's best known scientists, Paul Davies, conceded that, "There is no know law of physics able to crate information from nothing." And perhaps that's why, in a New Scientist article, he lamented, "How did stupid atoms spontaneously write their own software? Nobody knows."

Characteristics of Life

Life is difficult to define, but there are characteristics of life that can be explored! Join the Amoeba Sisters as they explore several characteristics of life. Click "show more" to expand video details to see table of contents & additional information. 👇 We chose not to give a numerical value for how many characteristics of life there are, because we do not want to imply that what we are listing must be a specific order, or that it cannot be expanded upon or include exceptions. Additionally, characteristics can also certainly be titled differently. Our goal is to promote thought and discussion about what it means for an organism to be alive as well as provide characteristics of life that can be explored when trying to study living things. CHARACTERISTICS OF LIFE MENTIONED IN THIS VIDEO: Organization (all life is composed of 1 or more cells) 2:20 Homeostasis 2:54 Metabolism (including need to obtain+use energy) 3:35 Reproduction 4:22 Growth and Development 4:46 Response to Stimuli 5:10 Evolution (occurs in populations, can lead to adaptation) 5:58 While living organisms tend to have ALL of the above characteristics, there are exceptions (such as the 'zonkey' mentioned in video at 6:55). *Quote Citation: Mullen, Leslie.

Thanks to original content developers.

It is a growing field of research that aims to discover innovative cancer immunotherapies to treat and retard progression of the disease. The immune response, including the recognition of cancer-specific antigens is of particular interest in the field as knowledge gained drives the development of new vaccines and antibody therapies. For instance in 2007, Ohtani published a paper finding tumour infiltrating lymphocytes to be quite significant in human colorectal cancer. The host was given a better chance at survival if the cancer tissue showed infiltration of inflammatory cells, in particular those prompting lymphocytic reactions. The results yielded suggest some extent of anti-tumour immunity is present in colorectal cancers in humans.

'Protein Packing' strives to more accurately depict the molecular chaos in each and every cell, with proteins jittering around in what may seem like random motion. Proteins occupy roughly 40% of the cytoplasm, creating an environment that risks unintentional interaction and aggregation. Via diffusion and motor protein transport, these molecules are directed to sites where they are needed.

Tumor antigens are useful in identifying tumor cells and are potential candidates for use in cancer therapy. Normal proteins in the body are not antigenic because of self-tolerance, a process in which self-reacting cytotoxic T lymphocytes (CTLs) and autoantibody-producing B lymphocytes are culled "centrally" in primary lymphatic tissue (BM) and "peripherally" in secondary lymphatic tissue (mostly thymus for T-cells and spleen/lymph nodes for B cells). Thus any protein that is not exposed to the immune system triggers an immune response. This may include normal proteins that are well sequestered from the immune system, proteins that are normally produced in extremely small quantities, proteins that are normally produced only in certain stages of development, or proteins whose structure is modified due to mutation.

Secrets Of The Human Cell "The DNA from a single human cell contains about 3 billiion "letters." "If the DNA from all the cells in the human body was stretched out and laid end to end, it would reach to the moon and back - a distance of more than 435,000 miles." Books - Bruce Lipton: Biology Of Belief Spontaneous Evolution http://www.brucelipton.com "Until now, this stored information has been inaccessible to us except for initiates of mystery schools, spiritual masters, and holy persons dedicated to serving the Light. Our human form is composed of 12 physical strands of DNA and 12 corresponding spiritual strands, totaling 24 strands. The average person has only one strand of DNA activated, which relates to 10% brain use in humans. Herein lies the reason why people use so little of their brain capacity." -Cheryl Caccialanza http://www.astrostar.com/articles/ 22StrandDNA.htm "Some biologist describe DNA as an "ancient high biotechnology," containing "over a hundred trillion times as much information by volume as our most sophisticated information storage devices." Could one still speak of a technology in these circumstances? Yes, because there is no other word to qualify this duplicable, information-storing molecule. DNA is only ten atoms wide and as such constitutes a sort of ultimate technology: It is organic and so miniaturized that it approaches the limits of material existence."

Over the past 10 years there has been notable progress and an accumulation of scientific evidence for the concept of cancer immunosurveillance and immunoediting based on (i) protection against development of spontaneous and chemically-induced tumors in animal systems and (ii) identification of targets for immune recognition of human cancer. Cancer immunosurveillance is a theory formulated in 1957 by Burnet and Thomas, who proposed that lymphocytes act as sentinels in recognizing and eliminating continuously arising, nascent transformed cells.[2][3] Cancer immunosurveillance appears to be an important host protection process that decreases cancer rates through inhibition of carcinogenesis and maintaining of regular cellular homeostasis.[4] It has also been suggested that immunosurveillance primarily functions as a component of a more general process of cancer immunoediting.

Angelika Amon (MIT and HHMI) Part 2: Effects of Aneuploidy on Cell Physiology
 
36:54
https://www.ibiology.org/cell-biology/review-study-autosomal-aneuploidy/#part-2 Overview Amon begins her talk by explaining what aneuploidy is and how it arises. She explains that autosomal aneuploidy is usually devastating to an organism, while aneuploidy at a cellular level may result in the unrestricted growth seen in cancer. In Part 2, Amon provides more details about the impact of aneuploidy on individual cells. Using budding yeast and mouse lines engineered to have specific aneuploidies, Amon's lab was able to show that aneuploid cells show gene specific effects, as well as a higher overall level of cellular stress. Part 3 focuses on the role of aneuploidy in disease, specifically in cancer. Amon discusses how identifying enhancers and suppressors of the aneuploid condition can shed light on the effects of aneuploidy in cancer and can lead to the development of novel cancer therapeutics. Biography Angelika Amon received both her B.S. and Ph.D. degrees from the University of Vienna. She was a post-doctoral fellow at the Whitehead Institute and was subsequently named a Whitehead Fellow. In 1999, she joined the Massachusetts Institute of Technology where she is currently Professor of biology and Kathleen and Curtis Marble Professor in cancer research at the Koch Institute. Amon is also an Investigator of the Howard Hughes Medical Institute. Amon's lab uses budding yeast as a model to understand the regulatory mechanisms that ensure the correct segregation of chromosomes during mitosis and meiosis. Her lab also investigates what happens when correct segregation fails and aneuploid cells are formed. She studies these questions in budding yeast, mouse and humans. Amon is a recipient of many honors and awards including the Alan T. Waterman Award of the NSF. She was elected to the National Academy of Sciences in 2010.

Dominique Bergmann (Stanford U / HHMI) 2: Stomata as a model for stem cells
 
34:27
https://www.ibiology.org/plant-biology/stomata/#part-2 Talk Overview: While mammals are protected by the mother’s womb during their most critical development, plants are exposed to the environment for most of their development. To survive, plants have developed strategies such as the ability to grow new tissue and regenerate tissue lost to predators. New leaves, stems and flowers are derived from the shoot apical meristem while roots come from the root apical meristem. Meristems are the source of pluripotent stem cells for all plant growth. Bergmann explains that because plants can live for a very long time and are constantly regenerating they are an excellent system for improving our understanding of stem cells. In Part 2, Bergmann focuses on the stem cells that give rise to the epidermis of the plant. These stem cells give rise to two distinct sets of cells. Pavement cells form an impermeable layer that “waterproofs” the plant. Stomata are small pores on the plant surface formed by two cells that act as a valve to regulate the uptake of CO2 and the release of oxygen and water. Bergmann’s lab used confocal microscopy to follow stem cells from their “birth”, through a series of asymmetric divisions to their eventual differentiation to pavement cells or stomata. At the same time, they measured how active or inactive all genes in the plant were at the different stages. Using chromatin immunoprecipitation, they were able to identify key genes involved in determining and maintaining cell fate decisions. Interestingly, similar genes and mechanisms may influence cell fate decisions in animals. In her last talk, Bergmann discusses the impact of plant physiology on the Earth’s climate and the impact of climate on plant physiology. Since stomata regulate CO2 uptake and oxygen and H2O release, their function impacts global climate change. The number of stomata a plant has increases and decreases in response to many factors including CO2 concentration, light, and temperature and stomata can open and close in response to the same cues. Bergmann and her colleagues studied plants with different numbers of stomata that were grown in controlled climates to get a better understanding of stomatal behavior in response to changes in climate. Knowing these details may contribute to improving the accuracy of global climate models.

PMID: 22691547 Speaker Biography: Dominique Bergmann completed her BA in molecular and cellular biology at the University of California, Berkeley. Bergmann studied development in C. elegans as a PhD student at the University of Colorado at Boulder, but switched her focus to development in Arabidopsis while a post-doc at the Carnegie Institution, Department of Plant Biology. Moving to Carnegie’s neighbor, Stanford University, Bergmann set up her own lab in 2005, and continues to study Arabidopsis. Currently, her work focuses on specialized structures called stomata and the role of asymmetric cell division and cell-cell communication in their formation. Bergmann is currently an associate professor at Stanford University and a Howard Hughes Medical Institute and Gordon and Betty Moore Foundation Investigator. She is also an associate of the Stanford Institute for Stem Cell Biology and Regenerative Medicine and The Carnegie Institute, Department of Plant Biology.

The smallest unit of life is the cell. This is a perfect start. A complex organism, like a human, cannot be fully understood without a grasp on the foundation. With this, Spontaneous Generation and The Law of Biogenesis are always brought up. These two concepts shape the way science approaches cells. Finally, a little light must be shed on Evolution. ______________________ www.jagilsdorf.com ______________________

How Scientists Found a New Neuron Hiding in Our Brains
 
03:20
This never-before-seen neuron was just found in the human brain, and it might hold the secret to what separates us from other animals. We Didn’t Think This Part of the Brain Existed, and It Could Save Your Life - https://youtu.be/RO3gTX1nlYE Read More: Meet the Rosehip Cell, A New Kind of Neuron https://www.wired.com/story/meet-the-rosehip-cell-a-new-kind-of-neuron/ “ On Monday, an international team of researchers introduced the world to a new kind of neuron, which, at this point, is believed to exist only in the human brain. The long nerve fibers known as axons of these densely bundled cells bulge in a way that reminded their discoverers of a rose without its petals—so much that they named them ‘rosehip cells.’” Scientists identify a new kind of human brain cell https://alleninstitute.org/what-we-do/brain-science/news-press/articles/scientists-identify-new-kind-human-brain-cell “In a new study published today in the journal Nature Neuroscience, Lein and his colleagues reveal one possible answer to that difficult question. The research team, co-led by Lein and Gábor Tamás, Ph.D., a neuroscientist at the University of Szeged in Szeged, Hungary, has uncovered a new type of human brain cell that has never been seen in mice and other well-studied laboratory animals.” Transcriptomic and morphophysiological evidence for a specialized human cortical GABAergic cell type https://www.nature.com/articles/s41593-018-0205-2 “ These rosehip cells show an immunohistochemical profile matching a single transcriptomically defined cell type whose specific molecular marker signature is not seen in mouse cortex. Rosehip cells in layer 1 make homotypic gap junctions, predominantly target apical dendritic shafts of layer 3 pyramidal neurons, and inhibit backpropagating pyramidal action potentials in microdomains of the dendritic tuft.” ____________________ Elements is more than just a science show.
