LIFE SCIENCE

Detailed explanation-1: -These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.

Detailed explanation-2: -Signals from the environment-chemicals, extracellular proteins/hormones/factors, neighboring cells, the physical environment-converge on the cell, typically activating a signaling cascade that leads to gene expression. These specific proteins change the phenotype into that of a more specialized cell.

Detailed explanation-3: -Stem cells used or targeted by cell therapy can be grouped into three categories: pluripotent stem cells (PSCs), adult stem cells (ASCs), and cancer stem cells (CSCs).

Detailed explanation-4: -Anemias (Aplastic Anemia, Congenital Dyserythropoietic Anemia, Paroxysmal Nocturnal Hemoglobinuria and Fanconi Anemia) Blood disorders or inherited red cell abnormalities (Blackfan-Diamond Anemia, Beta Thalassemia Major, Pure Red Cell Aplasia and Sickle Cell Disease) More items •25-Aug-2022
