BACKGROUND: By targeting inducing differentiation in vitro,mesenchymal.stem cells(MSCs) transform into osteoblasts,lipocytes,chondrocytes,muscular cells,neuronal cells,etc. Whether Chinese herbs act on induced differentiation of MSCs in rats or not?OBJECTIVE: To study the amplification of MSCs cultured in vitro in SD rats and efficacy of Chinese herbs on targeting inducing differentiation of neuron-like cells.DESIGN: Exploring study with repeated observation and measurement based on cells.SETTING: Department of pathophysiology in a medical college.MATERIALS: Experimental marrow collected from SD male tested-healthy rats.METHODS: By adhesion method,MSCs in rats were isolated for amplifying culture in vitro. Flow-type cell instrument was applied for the determination of its surface antigen expression. Various Chinese herbal components were used for the targeting inducing differentiation of MSCs into neuron-like cells. The cellular morphology was observed under optical microscope. and the specific antigen label of neuronal cells was determined with immunocyto-chemical method.MAIN OUTCOME MEASURES:①Results of MSCs isolation and amplification;②Results of identification of MSCs surface antigen and neuon-like cells.RESULTS: By adhesion method,MSCs in rats were isolated successfully and amplified in a large amount in vitro. It was indicated in the results determined by flow-type cell instrument that CD14,CD1 1α,CD34,CD38,CD45,CD80 and CD86 presented negative,and CD29,CD44,CD90,CD105 and CD166 presented positive. By induced with various kinds of Chinese herbs,like huangqi(Radix Astragali seu Hedysari),tianma(Rhizoma Gastrodiae),renshen (Radix Ginseng),danggui(Radix Angelicae Sinensis),naoxinshu,renshen fengwangjian for 1 to 3 hours,most MSCs transformed into neuron-like cells,presenting soma and neurite. With immunocyto-chemical staining,neuron-specific enolase(NSE) and nestin displayed positive and glial fibrillary acidic protein negative.CONCLUSION: MSCs in SD rats have the potential of multi-targeting differentiation,presenting a strong capacity of amplification and self-replacement. In a suitable inducing condition,MSCs may differentiate into neuron-like cells.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for the prenatal diagnosis of a fetus with structural anomaly detected by ultrasonography. METHODS: The fetus and its parents were subjected to chromosomal karyotyping and CMA analysis. RESULTS: The fetus was found to carry a 46,XN,t(8;11)(q21.2;q13) translocation which was inherited from its mother. CMA has found no copy number variations (CNVs) in both parents but a de novo 2.00 Mb microdeletion in the fetus at 8q13.3. CONCLUSION CMA is capable of detecting microdeletions and microduplications in fetuses with translocations detected by karyotyping analysis.
