In this lecture ´´Stem Cells and Renewal in Epithelial Tissue´´ is explained. Section one is about ‘‘Stem Cells’’. Initially, educator talks about Stem Cells. After that Types of Stem Cells are elaborated. Then Significance of Stem Cells is reported. Educator informs that a stem cell can become any one of the 220 different cells in the body.
Section two is about ''Epithelial Tissue''. Educator begins by explaining in detail the Lining of Small Intestine. Then Stem Cells in Small Intestine are pursued. Following this, Signaling Pathway is elaborated.
Intestinal Stem Cell Niche
Section three is about ''Intestinal Stem Cell Niche''. Educator's first subject of discussion is Paneth Cells. These cells are Slim and columnar. After that, Genesis of Minigut comes under consideration. In the end of this section, educator elucidates Ephrin–Eph Signaling.
Signalling Pathway Controlling Diversification
Section four is about ''Signalling Pathway Controlling Diversification''. Firstly, Notch Signaling is demonstrated. Moving on, Epiderma stem cell system is explained in detail.
Tissue Renewal Minus Stem Cells
Section five is about “Tissue Renewal Minus Stem Cells”. In this beginning of this section, beta cells are elucidated. Hepatocytes are then brought under discussion. In the end of this lecture, non renewable tissue are focused by the educator.
