Life Inside a Cell Animation
If you’ve ever wondered what goes on inside a cell, you might want to watch “Life Inside a Cell Animation.” This 3D computer graphics film is created by David Bolinsky, former lead medical illustrator at Yale, in collaboration with John Liebler and Mike Astrachan of XVIVO. This animation highlights the molecular interactions that occur when white blood cells are triggered by inflammation. The video begins with a white blood cell rolling along the inner surface of a capillary vein. As it advances, it shows the molecular structures of a leukocyte inside the cell.
Scientists have created an animation showing the motion of cells by studying the way microtubules assemble into tubes. These tubulin-based scaffolds allow cells to move and stay in place. When cells divide, microtubule fibers pull apart chromosomes, which are the basis of cell division. These hollow rods of tubulin are also important for anchoring cells and pulling chromosomes apart during cell division.
If you’ve ever wanted to know more about the inner workings of a cell, then you should check out the video below, made by medical animator David Bolinsky. It demonstrates the bustling molecular environment that occurs inside a cell. This animation explains the four steps of leukocyte extravasation. It also shows the structures in slow motion, such as a cell membrane, which is extremely dense and packed with molecular structures.
The production, The Inner Life of the Cell, shows the journey of white blood cells along the endothelium and their responses to external stimuli. It is the first in a series of cellular animations produced by Harvard University and XVIVO. In Powering the Cell: Mitochondria, you will follow the mechanisms of ATP production along the inner mitochondrial membrane. The series of animations explores the complex molecular environment in cells.
“Life Inside a Cell” is a fascinating animated video created by Harvard scientists. It establishes a cinematic look for educational scientific visualizations by combining compelling imagery with an emotionally moving soundtrack. It invites viewers to interact with material that is otherwise inaccessible to the general public. “The Inner Life of the Cell” took 14 months to make. It is one of the most popular animated videos of all time.
The immune system contains many types of leukocytes. The lymphocytes play a central role in immunological processes due to their antigen specificity, receptor diversity, and self/nonself recognition. Interactive galleries of cells and tissues illustrate the essential elements of the immune system and the anatomical sites of major organs. You will discover how these cells communicate with one another and with other cells in the body. In addition, the animation shows how different types of T-cells behave in the immune system.
Microfilaments provide rigidity to cells and depolymerize and reform quickly. For example, white blood cells move to the site of an infection to phagocytize pathogens. These white blood cells can engulf two bacteria in a single movement, and they also fight infections with the Human Immunodeficiency Virus.
A cytoskeleton is a complex network of proteins that provide rigidity and facilitate movement in cells. It anchors the nucleus, moves vesicles inside and outside of the cell, and pulls replicated chromosomes to the poles of dividing cells. Other components of the cytoskeleton include centrioles and flagella. Cyskeleton examples support Big Idea 1 of the AP Biology curriculum framework.
