Cell Based Therapy

Aims: cell-based therapy with bone marrow stem cells (MSCs) remains a viable option for tissue repair and regeneration. One of the major challenges for cell-based therapy is the limited survival of the cells after in vivo administration. The exact mechanism(s) for impaired in vivo survival of the implanted MSCs remains to be defined. Oxidized low-density lipid protein (ox-LDL) is a natural product in human blood, and the major contributor to the development of atherosclerosis. The present study was to investigate the effect of ox-LDL on the survival of bone marrow stem cells and the mechanisms in vitro. Methods and Results: Rat bone marrow multipotent adult progenitor cells (MAPCs) were treated with ox-LDL (with the final concentration of 10 and 20 ug/ml) for up to 48 hours. Exposure to ox-LDL resulted in significant cell death and apoptosis of MAPCs in association with a significant increase in LDH release in the conditioned media in a dose- and time-dependent manner, indicating significant cell membrane damage. The membrane damage was further confirmed with the rapid entry of the small fluorescent dye FM1-43 as detected using confocal microscope. Ox-LDL generated a significant amount of reactive oxygen species (ROS) in the culture system as measured with electron paramagnetic resonance spectroscopy. The antioxidant N-acetylcysteine (NAC, 0.1 mM) completely inhibited the production of ROS from ox-LDL. However, it didn’t prevent ox-LDL-induced cell death or apoptosis. However, pre-treatment of the cells with the specific membrane protective recombinant human MG53 protein (rhMG53)(66 ug/ml, final concentration) significantly, reduced LDH release and the entry of FM1-43 dye into the cells exposed to ox-LDL. Conclusion: Ox-LDL enhanced cell death and apoptosis of MAPCs with a mechanism independent of ROS generation in vitro. Ox-LDL impaired the survival of MAPCs partially through cell membrane damage in vitro.

Endogenous Spleen Colonies

The effects of phytohemagglutinin (PHA) were studied in irradiated mice to see if a definite myeloproliferative effect could be demonstrated in vivo. The data obtained suggested the following conclusions. PHA treatment of the bone marrow donor only, causes a consistent but slight reduction in transplantable spleen colony-forming unit (CFU) content of the bone marrow 24 hr after the last PHA injection, but no change was found in the proportion of the various colony types. PHA treatment of the irradiated recipient of normal bone marrow causes no change in the number of spleen colonies. However, 8-day colonies are only about half normal size, are much more likely to be of mixed cell types, contain many large undifferentiated blastoid cells, but fewer transplantable CFU. The spleen sinusoids are packed with hemopoietic cells. Spleen colonies developing in hosts receiving daily injections of PHA show, in addition to the usual spectrum of cell types, a high proportion of unusual blastoid cells resembling the PHA transformed peripheral lymphocytes seen in vitro. The function of these cells is not known, but they may represent augmented proliferation and/or transformation of stem cells. PHA administered after irradiation significantly increased the number of endogenous spleen colonies, and, at certain doses of irradiation, improved postirradiation survival. PHA administered before irradiation had no effect on the number of endogenous spleen colonies formed, or on postirradiation survival. On the basis of these and other data, possible modes of action of PHA are discussed.

The study described a novel bone tissue scaffold fabricated by computer-aided, air pressure-aided deposition system to control the macro- and microstructure precisely. The porcine bone marrow stem cells (PBMSCs) seeded on either mPEG-PCL-mPEG (PCL) or mPEG-PCL-mPEG/hydroxyapatite (PCL/HA) composite scaffold were cultured under osteogenic medium to test the ability of osteogenesisin vitro. The experimental outcomes indicated that both scaffolds possessed adequate pore size, porosity, and hydrophilicity for the attachment and proliferation of PBMSCs and the PBMSCs expressed upregulated genes of osteogensis and angiogenesis in similar manner on both scaffolds. The major differences between these two types of the scaffolds were the addition of HA leading to higher hardness of PCL/HA scaffold, cell proliferation, and VEGF gene expression in PCL/HA scaffold. However, thein vivobone forming efficacy between PBMSCs seeded PCL and PCL/HA scaffold was different from thein vitroresults. The outcome indicated that the PCL/HA scaffold which had bone-mimetic environment due to the addition of HA resulted in better bone regeneration and mechanical strength than those of PCL scaffold. Therefore, providing a bone-mimetic scaffold is another crucial factor for bone tissue engineering in addition to the biocompatibility, 3D architecture with high porosity, and interpored connection.
