Question

Stem cells can potentially repair damaged tissue. One major challenge is how to _____.

Answer 1

The stem cells is defined as those cells that have the capacity to convert into any cells of the body . They are partially or the undifferentiated cells. They can divide into their daughter cells that have the same property of regeneration into different type of cells . They are epiblast derived stem cells , embryonic stage stem cells . They convert and differentiated into three layers known as Mesoderm , ectoderm , endoderm . They divide indefinitely into may structures and forms . There are various uses of the stem cells in the diagnosis of the diseases . By diagnosis the development of Muscles , bones , heart the disease causes can be easily find out . It is also used for the regeneration of certain tissues and organs such as the stem cell therapy in spinal cord lesions injury , type 2 diabetes mellitus , Parkinson's disease , Cancer , leukimea , arthritis and many cases . It is used in the implantation process .
There are various major issues that are associated with the stem cells differentiation of stem cells into a certain structure . The stem cells are present in very less number . The controlling of the stem cells is very difficult to direct the stem cells to a particular structure . The identity , isolate and triggering of the stem cells are very difficult . The other difficulty is the introduction of the stem cells into the patients body for eg :- if a cardiac stem cells is introduced into the patient body , then the beat sync with the patients own heart is a challenging phenomenon .if a neural cells is introduced then the neural cells should be able to make synapsis with the natural connections present in the spinal cord or other nerve fibres .
