The formation process of the terminal blood bed of the greater omentum has been studied in 42 human fetuses 14--28-week-old. The main peculiarities of the greater omentum blood bed by the 14th week of development are: paired arrangement of the afferent and deferent blood vessels and loop-shaped type of capillary growth, that joining the arteriole and venule, lend the blood stream a maximally centralized character. In 15--16 weeks of the fetal development in the omentum another type of the vascular growth occurs, characterized with appearance of single angioblastic processes that branch off the apex of the capillary loops. As a result new capillaries form; they connect apices of the capillary loops, that in their turn make bases for developing a true capillary network. Together with this, presence in ontogenesis of an autochthonous way of capillary appearance is proved, their connection with the closed blood stream is followed. Distinguishing of the loop-shaped stage in the capillary growth determines certain difference between vasculogenesis in ontogenesis and the vascular growth at reparative regeneration, since the base for the latter is only the capillary growth by means of single angioblastic processes.
对42例14至28周龄的人类胎儿大网膜终末血床的形成过程进行了研究。在发育第14周时，大网膜血床的主要特点是：传入和传出血管成对排列，毛细血管呈环状生长，连接小动脉和小静脉，使血流具有最大程度的集中特征。在胎儿发育的第15至16周，网膜中出现了另一种血管生长类型，其特征是单个成血管细胞突起从毛细血管环的顶端分支出来。结果形成了新的毛细血管；它们连接毛细血管环的顶端，进而为真正的毛细血管网络的发育奠定基础。与此同时，证明了在个体发育中存在毛细血管出现的自主方式，其与封闭血流相连接。毛细血管生长中环状阶段的区分决定了个体发育中的血管发生与修复再生时的血管生长之间存在一定差异，因为后者仅以单个成血管细胞突起的毛细血管生长为基础。
