摘要: Abstract Mesenchymal stem cells (MSCs) have the capacity to generate multiple tissues of mesodermal origin, and also potential trans-differentiate into neurons. We isolated MSCs from Wharton’s jelly human umbilical cord (WJ-MSCs), efficiently induced WJ-MSCs neuron-like using a modified method. After neuronal induction for 12 days, most expressed mature marker MAP2 (83 ± 7%), meanwhile some adopted morphology. Nestin (34 ± 6%), NSE (30 ± 5%), GFAP (12 ± 3%). Moreover, we used miRNA microarray analyze differentially miRNAs in differentiation WJ-MSCs. Microarray analysis revealed discrepant profiles uninduced derived Six were chosen further qRT-PCR validation. Among these 6 miRNAs, four (miR-1290, miR-26b, miR-194, miR-124a) up-regulated 2 (miR-4521 miR-543) down-regulated In conclusion, could be cells. More importantly, our findings suggested that might play important roles
