Background: Mesenchymal stem cells (MSCs) can provide therapeutic benefits for myocardial infarction (MI) recovery; however, the molecular mechanism by which MSCs improve the heart function is unclear.
Methods: Microarray analysis was performed to examine the expression profiling of human MSCs (hMSCs) grown as adherent cultures (AC-hMSCs) or nonadherent cultures on ultra-low-adherent plates (nonAC-hMSCs). Real-time quantitative polymerase chain reaction (RT-qPCR), western blotting, and enzyme-linked immunosorbent assays (ELISA) were used to assess VEGFA expression and secretion in the AC-hMSCs and nonAC-hMSCs.
Mesenchymal stem cells (MSCs) are routinely isolated due to their adherence to tissue culture plates and their in vitro growth characteristics. Expansion of MSCs in adherent cultures is the only way to obtain sufficient cells for use in either clinical or research settings. MSCs have tremendous potential in myocardial repair treatment by cell therapy techniques, however, a large number of MSCs die from apoptosis following transplantation.

Methods: The medical records of the patients developing digestive tract leak after surgery for esophageal carcinoma in our hospital from January 2003 to March 2011 were retrospectively analyzed.
Results: A total of 36 patients were included, in whom 13 developed cervical anastomotic leak, 18 had intra-thoracic anastomotic leak, and 5 had intra-thoracic gastric necrosis.
