摘要:

为了在体外细胞水平模拟多浪绵羊肌肉生长发育过程,本研究以多浪绵羊为试验动物,采用胶原酶和胰酶两步酶消化法分离多浪绵羊骨骼肌卫星细胞(satellite cells,SCs),并利用差速贴壁的方法纯化分离得到的SCs。利用免疫荧光技术检测SCs标记基因DesminPax7和MyoD1的表达情况,鉴定分离得到的SCs。采用血清撤离的方法诱导SCs向成肌方向分化。通过显微镜观察和成肌分化标记基因肌球蛋白重链(myosin heavy chain,MHC)的免疫荧光,检测肌管的形成情况。通过对SCs标记基因DesminPax7和MyoD1的免疫荧光鉴定,确认本研究成功分离得到多浪绵羊SCs。采用血清撤离的方法诱导SCs成肌分化,显微镜观察和MHC免疫荧光可以明显观察和检测到肌管的形成。本研究对多浪绵羊SCs成功地进行了分离和鉴定,并建立了体外培养条件下多浪绵羊SCs的成肌诱导分化。

Abstract:

To mimic muscle development of Duolang sheep in vitro,we employed a two-step digestion method to separate satellite cells(SCs)and a differential adhesion method to purify the cells in Duolang sheep.Moreover,observation of microscopic images and immunofluorescence were used for identifying Duolang sheep SCs and its myogenic differentiation.Using immunofluorescence for Desmin,Pax7 and MyoD1 genes,we demonstrated that these marker genes all expressed in the SCs.The SCs formed significant myotubes when the serum was withdrawal from growth media,confirmed by the immunofluorescence for MHC and microscopic images.Taken together,we ssuccessfully isolated SCs and established the myogenic differentiation of SCs.

Key words: sheep; skeletal muscle satellite cell; isolation and culture; myogenic differentiation
