Objective To establish a good method and culture system to isolate skin stem cell and expand it in vitro so as to lay a foundation for exploring the proliferation and differentiation mechanism of skin stem cell. Methods Skin stem cells were obtained by explant culture and identified by using alkaline phosphatase(ALP) staining and differentiating experiment in vitro. Stem cell was induced by the cocktail of conditional medium with cell growth factor (insulin like growth factor and epidermal growth factor). Results Skin stem cell colonies were derived from ear skin tissues of adult dairy goats. The colonies had some characteristics of embryonic stem cells, such as the ability to be continously passaged (Passage 5) and the morphology nest-like. They continued to be ALP positive and had the capacity of forming embryoid bodies. These cells were pluripotent and stem-like cells. In vitro these stem cell can be induced to be Follicle-like structure, Astrocyte-like cells, osteoblast-like cell. Conclusion Explant culture is a good method to isolate skin stem cell, which can be induced to be committed differentiation and trans-differentiation.

In Shaanxi, some medical institutions especially the primary medical institutions, have outstanding problems such as unbalanced and inadequate development of infection prevention and control efficiency. The concept, knowledge and attention of infection prevention and control of the medical institution managers need to be improved. With the strong support of the health administration department, the Infection Control Professional Committee of Shaanxi Provincial Preventive Medicine Association has given full play to its functions and explored innovative service models for infection prevention and control in recent years. This paper is written to share the measures and achievements for building a multi-dimensional leadership improvement platform to improve the infection prevention and control ability, aiming to offer a reference for other medical institution managers and infection prevention and control professionals.
