ABSTRACT
Mesenchymal stem cells (MSCs) have broad application potentials in regenerative medicine and translational medicine. Obtaining large quantities of primary-cultured MSCs and select the most suitable cell origin for targeted diseases are critical to research. To select the most suitable seed cells of MSCs from different origins for clinical treatment and research, biological characteristics of MSCs from human umbilical cord and placenta were compared. These include cell morphology, surface marker expression, differentiation and karyotype. Transcriptome sequencing of four MSCs from fetus were performed and the results were analyzed from the perspective of proliferation and cytokine secretion. The results revealed that MSCs from umbilical cord (UC), amniotic membrane (AM), chorionic membrane (CM), chorionic villi (CV) and deciduae (DC) met the minimum standards of the International Society of Cell Therapy (ISCT) in 2006 and had the general characteristics of stem cells. Karyotype analysis showed that MSCs derived from UC, AM, CM and CV were all from fetus except that the DC-MSCs were from mother. Transcriptome sequencing analysis showed that hMSCs from umbilical cord and placenta had similar gene expression patterns, while different expression patterns were observed in specific genes involved in cell cycle, cell division, cell death, cell growth and development. These genes play important roles in transcriptional regulation, DNA repair, DNA replication and chromosome stability, which were momentous components of cellular or subcellular fraction movement, cell communication, cell tissue protrusions, cytokine secretion and hormone metabolism. Transcriptome sequencing analysis explained the differences in biological characteristics among MSCs from different sources, while verification experiments based on the transcriptome sequencing results showed that the proliferation and cytokine secretion capabilities of MSCs from different sources were significantly different. In all, UC-MSCs and CV-MSCs with stronger proliferation and higher levels of paracrine factors secretion may show their respective advantages in treating diseases.
