Stem cells : a paracrine effect in heart failure 干细胞：心力衰竭时通过旁分泌发挥作用？

Owing to the common expression of egf in various organs of mouse , it could be deduced that the role of egf was mainly autocrine and paracrine actions , and its endocrine role was also not excluded owing to its high expression abundance in submaxillary gland 由于egf在小鼠各器官中表达的普遍性，可以推测egf的作用以旁分泌和自分泌作用为主，但它在颌下博士学位论文“ tnegfalelittin ”嵌合基因构建及有关基因重组表达的研究等器官中的高表达表明其也具有内分泌作用。

The vascular endothelium is the biggest endocrine and paracrine organ in human body , it has an important physiological function ; vascular endothelial dysfunction is associated with hypertension , and it provides prognostic information in the hypertensive patients ; there are many means to assess vascular endothelial dysfunction , but the most optimal methodology is still under debation 血管内皮是人体最大的内分泌、旁分泌器官,有重要的生理功能;高血压与血管内皮功能不全密切相关,血管内皮功能不全对高血压的预后有预测价值;评价血管内皮功能不全的方法虽多,但还缺乏最理想的方法。

It requires further investigation whether spermatogonial proliferation starts in november . 3 . interstitial cells synthesize t in spring and autumn , its spermatogonial proliferation independent on the levels of t . t in the follicular cells in the testis of rana quadranus regulate sperm maturation by paracrine mechanism 隆肛蛙因对寒冷的气候很敏感，在外界活动的时间短，使其从精原细胞到成熟精子发育的时间很短，精原细胞很快增殖并进行成熟分裂而成为成熟精子。
