[1]
In addition to the surviving tubular epithelial cells and kidney stem cells, the bone marrow stem cells have also been shown to participate in regeneration of the proximal tubule, however, the mechanisms remain controversial. Studies examining the capacity of bone marrow stem cells to differentiate into renal cells are emerging. [34]

cell suicide, also known as apoptosis or programmed cell death; unregulated cell division, which can lead to the formation of a tumor that is cancerous; The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism.
Homology-directed repair (HDR) is a mechanism in cells to repair double-strand DNA lesions. [1] The most common form of HDR is homologous recombination. The HDR mechanism can only be used by the cell when there is a homologous piece of DNA present in the nucleus, mostly in G2 and S phase of the cell cycle. Other examples of homology-directed ...
