WebSep 1, 1989 · ABSTRACT. In most regenerating systems, blastema cells arise by dedifferentiation of functional tissue cells. In planarians, though, it is still debatable whether dedifferentiated cells or a population of undifferentiated cells, the neoblasts, are the main source of blastema cells. Moreover, it is unclear whether in the intact organisms …
