With Mab 2A3, the first positive cells were detected at the limb bud stage of the embryos. Distinguishable positive haemocytes with a diameter of about 7μm appeared in embryonic-nauplius. At the following nauplius I stage, configuration of haemocytes became more integrated and clear. Their diameters were almost similar to those of haemocytes from adult shrimp. With Mab 1H11, the first positive granular haemocytes were identified at the stage of embryonic-nauplius which existed in clusters with positive punctate fluorescence of granules distributed around the periphery of granular haemocytes.

通过对包括囊胚期、原肠胚期、肢芽期、膜内无节幼体期和无节幼体Ⅰ期在内的中国对虾胚胎的间接免疫荧光检测，最早在肢芽期胚胎中检测到2A3阳性信号；在膜内无节幼体期，2A3阳性血细胞平均直径约7μm，聚集成簇；在无节幼体Ⅰ期，血细胞形态更加完整清晰，平均直径已与成体对虾血细胞相似。1H11阳性大颗粒细胞最早在膜内无节幼体期胚胎中出现，这些细胞同样成簇存在，在其细胞质外围可见点状荧光。
