- 眼科医生 眼科 眼科
- 生物材料科学 生物材料科学
- 再生医学是一种再生医学.
背景情况:
- 膜切除通常需要结膜重建.
- 需要新的生物材料来改善移植结果.
- 脱细胞化结膜层 (DCS) 是羊水膜 (AM) 的潜在替代品.
研究的目的:
- 为了比较脱细胞化结膜层 (DCS) 与羊水膜 (AM) 在初级切割后结膜重建的疗效和安全性.
- 为了评估移植结果,视力敏度和患者的症状.
主要方法:
- 一项随机的,并行控制的研究招募了40名患有初级的患者.
- 患者接受了DCS (n=20) 或AM (n=18) 移植.
- 评估包括裂纹灯摄影,最佳校正视敏度 (BCVA),症状得分和体内共聚焦显微镜.
主要成果:

Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Cells of the Epidermis
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
