Amino-PVA-SPION alone was detectable in cytoplasmic endosome-like structures after 3 hours of incubation but resulted in early cell death after 24 hours. 经过三个小时的培养后,单个的氨基化PVA-SPION能在细胞质的类内含体结构中被探测到,但是24小时后却造成了早期细胞的死亡。
Major components of a plasmodesma (PD) include a plasma membrane, a desmotubule, and a cytoplasmic annulus, all of which are readily detectable by electron microscopy. 胞间连丝的主要构成部分是细胞质膜、连丝小管、以及位于二者之间的环层细胞质。
