Beyond Science: Cell Biology - Stem Cells

Understand Stem Cells in 6 minutes with Sarah from Beyond Science. Subscribe for updates: https://www.youtube.com/channel/UC52a... By the end of this lesson you will be able to describe the function of stem cells in embryos, in adult animals and in the meristems in plants. You'll be able to discuss the benefits and risks of using stem cells to treat conditions such as diabetes and paralysis. Sarah explains that a stem cell is a cell that hasn't been differentiated in any way. She mentions stem cells ability to replicate and make more stem cells. Describing how they can differentiate and become different types of cell such as: a red blood cell, a root hair cell and a nerve cell. From here, Sarah explains how in animals, cells differentiate early in the organisms life cycle, this means that animals like humans have many stems cells during their early development as embryos. As the embryo develops stem cells differentiate to form any of the different cells that the body will need as it grows. Sarah also describes how some adult stem cells are found in bone marrow and have the ability to differentiate, but are less varied. She explains that stem cells can be used to treat some medical conditions; exploring the benefits and problems of adult stem cell therapies.
