红素 (EPO) 在训练后10分钟内通过全身注射.
记忆回忆被评估在不同的时间点 (24小时到21天).
在前额皮质和海马体中分析了arc和bdnf的基因表达.

主要成果:

学习增加了内源性EPO和EPO受体 (EPOr) 表达,与记忆持续时间相关.
外源性EPO的使用延长了长达21天的记忆保留.
使用EPO调节了bdnf在前额叶皮层 (24小时) 和海马体 (21天) 的表达.

Clinical Applications of Epidermal Stem Cells

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...
