Cellula staminale - Wikipedia

Research has been ongoing now for years as scientists have tried to determine whether stem cells from adult tissues have the same capabilities and potential as embryonic stem cells. Studies are constantly revealing new information and it is hoped that therapeutic applications will be developed from both sources. The question, however, perhaps remains: which source holds the advantage? Development Potential Adult stem cells are generally less flexible and versatile than embryonic stem cells.

Stem Cells: General Features and Characteristics

By definition, stem cells are cells that individually or as a population can produce differentiated progeny and reproduce themselves Slack More specifically, they can divide without limit, are not terminally differentiated, can be either unipotent , pluripotent, or totipotent , and upon division, daughter cells can either become another stem cell or begin a process of terminal differentiation. In this article I will explore the similarities and differences between two stem cell types, adult and embryonic, both of which are being aggressively investigated for their potentially invaluable medical implications.

What is an embryo? An embryo is formed within 5 days after an egg is fertilized by a sperm cell. Embryonic stem cells at this very early stage contain all the material necessary for the complete development of a human being. This is truly a marvel of the human body! As the cells multiply the inner mass of cells will become the developing embryo, and the outer cells the placenta.
