1·Purpose to isolate and culture rat mesenchymal stem cells and induce rat MSCs into photoreceptor cells in-vitro.
目的分离培养大鼠骨髓间充质干细胞，尝试在体外将其诱导为光感受器细胞。
2·There were many photoreceptor Like structures and tiny fits similar to nerve palpate or neurilemma in the tissues of the tumor, especially many filaments and microtubules in the tumor cells.
特别提出肿瘤组织中有光感受器样结构，以及类似神经触突或神经髓鞘的微细装置。尤其是很多肿瘤细胞里面有大量的微丝、微管。
3·Photoreceptor loss caused by degeneration in the pigmented layer of the retina (RPE cell layer) eventually leads to blindness.
光感受器丧失引起的色素变性在层(RPE细胞层视网膜)最终导致失明。
