It leads to one simple equation, which, in the isotropic case, is the bipotential equation . 因为它可以推出一个简单的方程,在各向同性的情况下,这个简单方程是一个双位势方程。
Bipotential electrostatic lens 双电势静电透镜
Conclusion : hpfl shows the characterization of stem cell : excellent capability of proliferation and bipotential differentiation 研究结论: hpfl具有干细胞的一般特性:具有很强的体外扩增和双向分化能力。
If alb + ck - 19 - cells would be induced into alb + ck - 19 + cells , we can prove that hpfl contain bipotential stem cells . 3 ) primary hpfl seeded on pref feeder layer were collected and engrafted into the spleen of sced mice to explore the propagation of hpfl in vivo 3 )收集在原代大鼠成纤维细胞( pref )饲养层上培养的原代hpfl ,注人scto鼠脾脏,观察hpfl植人体内的增殖发育情况)将分离的大鼠ed13
