Lymphoid stem cells can produce a few, but not all, kinds of blood cells. Finally, cells that only produce identical copies of themselves are called unipotent. Like skin cells, when they divide, they only make more skin cells.

淋巴干细胞可不像造血干细胞那样能造出所有血液类型的细胞，它们只能创造复制出自身相同的细胞，比如皮肤细胞，当它们分裂的时候，只能够制造皮肤细胞，我们把这些干细胞叫单一干细胞

RESULTS: hADSCs presented fibroblast-like morphological feature with a flocked array. The 3rd passage of hADSCs had unique immunophenotypes and they were positive for CD73, CD44, CD166, CD105 and CD29, but negative for CD31, CD34, CD45 and HLA-DR. Cell cycle result showed that they had the typical growth characteristics of stem cells, namely, 83.81% cells stayed at G0/G1 stage, only 16.19% cells were stayed at S+G2/M stage; The latent phase of the primary culture cells was 2 days prior to and after incubation, followed by 3-6 days of logarithmical proliferation, reached a peak at day 6, and entering the growth platform phase with lower growth speed.

结果：分离培养的人脂肪间充质干细胞为成纤维细胞样，呈漩涡状排列。P3代人脂肪间充质干细胞呈CD73，CD105，CD166，CD44及CD29阳性，而CD31，CD34，CD45及HLA-DR阴性；具有典型的干细胞增殖特点，83.81%细胞处于G0/G1期，仅16.19%细胞处于S+G2/M期；细胞在接种后前2 d处于生长潜伏期，第3~6天处于对数生长期，第6天达峰值，以后细胞生长速度减慢，进入生长平台期，平均五六天传代1次。

To mensurate the expression of MDR1 of different breast cancer cells from human breast cancer primary cells and MCF-7 breast cancer cell line,and the kill effect of chemotherapy drug with different breast cancer cells in vitro,and the change of the proporation and the expression of MDR1 of breast cancer stem cells after chemotherapy.

测定人乳腺癌标本和MCF-7中不同细胞亚群的MDR1表达情况；并测定化疗药物在体外对人乳腺癌原代细胞和MCF-7中不同细胞亚群的杀伤作用，以及在化疗药物干预后，乳腺癌干细胞的含量和MDR1表达的变化情况。

The adipose derived stem cells of inbreds train of rat wereinduced to differentiate into schwann-like cells and the cells were injectedinto the acellular nerve allograff.The proliferation or adhersion of these cells on the graft were observed by inverted microscope or ScanningElectronic Microscope. Activity of cells were detected using MTT. 10mmnerve gap of inbreds train of rats in two group were bridged by tissue-engineered peripheral nerve or autogenous nerve, the effect wereappraised by naked eye, recovery rate of sciatic function index,nerve-electrophysiological, histology, Transmission ElectronMicroscopy and quantitative analysis of recovery rate of myelinated fiberpopulations,diameter of myelinated fiber and thickness of myelin sheat.
