Overview:
c-KIT (Y823D) encodes the ligand-binding chain (alpha) of the gamma interferon receptor which is a heterodimer of IFNGR1 and IFNGR2. c-KIT (Y823D) is a regulator of hematopoietic stem cells during homeostasis and under conditions of infectious stress. A genetic variation in c-KIT (Y823D) is associated with susceptibility to Helicobacter pylori infection. In addition, defects in c-KIT (Y823D) are a cause of mendelian susceptibility to mycobacterial disease, also known as familial disseminated atypical mycobacterial infection (1). c-KIT (Y823D is also associated with the clinical outcome of HBV infection in Chinese adults (2).
Gene Aliases:
PBT, SCFR, CD119

Bone Mesenchymal Stem Cells 作为一个细胞群体，还没有发现有特定细胞表面marker. 对于那些可以代表自我更新和分化的marker, 也不清楚到底要发现哪一个的表达才能确定该细胞就是BMSC。
目前常用的方法，就是采用培养，colony-forming unit-fibroblasts (CFU-F)这个方法。一般BMSC可以24-48小时贴壁。
流式细胞计数，比如STRO-1，但是一般认为STRO-1阳性的细胞更趋向于造血干细胞，和BMSC简单区别还不是很清楚。
这里有个培养分化的产品

下面的这段话是图注，图注的意思我明白，但是我想知道merge后的图看什么颜色的荧光，蓝色是细胞核，红色是lysosome(位于胞质），绿色是AMPKβ2，该实验是想观察AMPKβ2是否转位到lysosome上了，如果确实发生了AMPKβ2转位到lysosome上，那么merge后是红色与绿色融合在一起，是吗？融合在一起发什么颜色的光了？
