Stem Cells and Differentiation Flashcards
Define embryo
Early stage of human development in which organs are formed
Define foetus
A human embryo after six weeks of development
Define Blastocyst
An embryo that’s five or six days old
Define zygote
The diploid cell
Formed by the combination of two haploid gamete cells
What specific cells can ectoderm differentiate into?
Nueron, skin cells, pigment cells
What specific cells can mesoderm differentiate into?
Skeletal muscle, smooth muscle, cardiac muscle, red blood cells, bone cells
What specific cells can endoderm differentiate into?
Stomach cells, pancreatic cells, liver cells
What is a unspecialized cells?
Cells which do not serve a unique or particular function
What are unspecialized cells?
Cells which serve as a unique, particular function
What are differentiated cells?
The development of a stem cell into a specialized cell
What is self renewal?
The capacity to replicate without disrupting their ability to differentiate by producing both a copy of themselves and a differentiated cell and a copy of themselves when they replicate.
Outline the potency of totipotent cells?
The greatest of potency. Can differentiate into any cell type.
Outline the potency of pluripotent cells?
Stem cells that can differentiate into multiple cell typess
Outline the potency of multipotent cells?
Stem cells that can differentiate into a limited number of specialized cell types belonging to a specific organ or tissue.
Outline the potency of oligopotent cells?
Can transform into quite a limited number of specialized cells including B cells, T cells, and plasma cells.
