As callus was considered to occur from mature cells, it had been assumed that cells must dedifferentiate if they type callus to be able to acquire pluripotency. (cancercurehere.com)
2010). In this full case, no such pluripotency acquisition, or dedifferentiation, stage is necessary as these specialised cells may currently be in an extremely competent condition (Sugimoto et al. (cancercurehere.com)
1958). This means that that as the pericycle, using its putative specific properties, may be the primary contributor to cells culture-based regeneration, pluripotency could be wide-spread amongst vegetable cells. (cancercurehere.com)
