Explanation:
Cell specialization is the process of cell differentiation. In this process the generic or normal cells in the body change their specific forms and functions to perform certain specific tasks in the body. This varies with the cell type for example, in young development embryos the stem cells proliferate and differentiate to support the development of body parts and organs in the body whereas in the case of stem cells in adults are specialized to replace the worn out cells of the brain, bones, blood and heart. Thus the specificity of the stem cells varies during various stages of life span of an organism that is from birth till the death.
How the potential for specialization varies with cell type and how it varies over the life span of an organism concept can be explained using stem cells
- As a fertilized single egg cell termed a zygote grows and becomes matures into aa blastomere, this two stages contains cell type that are totipotent in nature meaning these cells can give rise to an entire organism.
- As the blastomere develops into a blastocyst and proceeds on into an adult, the cell types differentiate and become specialized becoming pluripotent meaning they can now give rise to the three germ layers.
- For some of the cells to be able to perform their basic function as the individual grow and develop, these cells differentiate again into multipotent, oligopotent and then unipotent cells.
An example is seen in the case of a totipotent stem cell - a pluripotent stem cell (can become any type of cell) - haematopoietic stem cell (potential to become any type of blood cell) - becoming oligopotent (differentiation is limited to the cell of its lineage - then becoming specialized to a particular type of blood cell (a unipotent cell).
