The correct answer to this open question is the following.
<em>Stem cells found in adult tissue, such as in the bone marrow, brain, muscle, skin, and liver, are only capable of</em> self-renewal.
Stem cells in adults have the possibility of self-renewal and multipotency. Cells in the body can renovate themselves many times and also can differentiate in different types. Stem cells also have the ability to repair damaged tissues.
They are capable of renewing and dividing (multiplying) themselves for long periods of time, they are unspecialized, and they can give rise to other specialized cell types. Hope this helps!! :)
Explanation: Integrins are proteins and are the principal receptors that attach the cell cytoskeleton to the extracellular matrix (ECM). Integrins by sense whether adhesion has taken place that is to say a cell can regulate the adhesive activity of its integrins from within.
Calcitonin stimulates the kidneys to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the kidneys to excrete calcium when calcium levels are too high.
