However, with the development of the times, the employment difficulty of college students is increasing significantly. Under such circumstances, how to use the guiding ideology of all-round education to play its value and role is a problem that every college needs to consider. All major universities are committed to guiding the employment of contemporary college students from the perspective of all-round education, so that students can have a clear goal in the process of employment. Today, we will discuss the problems students encounter in the process of looking for a job from the perspective of "all-round education", and how to improve this phenomenon to guide college students to better obtain employment, hoping to be helpful to the majority of students.展开更多

To understand the effects of BMPs on SVZa neural stem cells, in this study BMP4 at various concentrations was used to induce SVZa ,neural stem cells, aud the living cell labeling using BMP4 pronmtor conjugated with red fluorescence protein showed the expression of BMP4 dynamically. The results demonstrated that low BMP4 doses (1-5 ng/mL) promoted while high doses(10-100 ng/mL) inhibited the proliferation of SVZa neural stem cells, and BMP4 promoted neuron differentiation in the early stage (1-3 d), howeverm, it inhibited the neuron commitment after 4 d. Noggin, the antagonist of BMP4, blocked the physiological effects of BMP4. In OB, BMP4 is mainly to accelerate the progenitors to withdraw from the cell cycle and trigger the differentiation, and in RMS, it promotes the proliferation of committed progenitors and not differentiation, further in SVZa, BMP4 enhances astrocyte commitment.展开更多
