The morphological observations of cells of the basal region of seminal follicles, studies of 3H-thymidine and 3H-uridine incorporation and results of cytophotometric DNA determination have shown that during the larval development the cells which have morphological features of classical endomitosis in the differentiated state are reproduced. Their reproduction and polyploidization takes place in the definite, morphologically delineated zone in the basal region of seminal follicle. From the latter zone these cells migrate in the middle zone where they function. At the same time changes in their morphology are observed: cell flattening, chromatin loosening in the nuclei, appearance of morphologically distinct chromosomes. The level of 3H-uridine incorporation increases.
精卵泡基部区域细胞的形态学观察、³H-胸腺嘧啶核苷和³H-尿苷掺入研究以及细胞光度法DNA测定结果表明，在幼虫发育过程中，具有分化状态下经典核内有丝分裂形态特征的细胞得以繁殖。它们的繁殖和多倍体化发生在精卵泡基部区域明确的、形态上可界定的区域。这些细胞从后一个区域迁移到它们发挥功能的中间区域。与此同时，观察到它们的形态发生变化：细胞变扁平，细胞核内染色质松散，出现形态上明显的染色体。³H-尿苷掺入水平增加。
