The remaining renal parenchyma has been reduced to a thin shell of dense fibrous connective tissue, rare sclerotic glomeruli and moderate numbers of mixed inflammatory cells. parenchyma cell. The wound induces parenchyma cells near the cut surface to dedifferentiate into meristematic cells, which then divide and produce root apical meristems that form roots on the cutting. d.
