BACKGROUND: Rapid development of tissue engineering is the new hope of repairing bone defect so as to obtain complete bone regeneration,and rapid proliferation of seed cells is one of the important factors in it.OBJECTIVE: To evaluate the proliferation and osteogenic differentiation of human mesenchymal stem cells (MSCs) plated at different cell density during subculturing period.DESIGN: Repetitive measurement.PARTICIPANTS: The experiment was conducted in the Trauma, Burn and Combined Injury Laboratory of the Third Military Medical University of Chinese PLA between January 2003 and March 2004. MSCs were obtained from iliac bone bone marrow of the 5 healthy male volunteers by separation and proliferation.METHODS: The MSCs of second generation were inoculated at 8×103/cm2,3×103/cm2, and 8×102/cm2, respectively, and then the growth curve was drawn and analyzed. After 18 days of proliferation and culture, the increased amount of MSCs was recorded to analyze the post-proliferation growth curve and osteogenic ability.MAIN OUTCOME MEASURES: ①Growth curve of cells plated at different cell density; ②Results of alkaline phosphatase(ALP) staining and immunohistochemical staining of osteocalcin.RESULTS: Human MSCs from bone marrow were CD34 negative and expressed low level of ALP. Population doubling time was 40 hours after MSCs were plated at 8×103/cm2 and the number of the cells was expanded (51±13) times after 18 days. MSCs were expanded (28±6) times 18 days after plated at 3×103/cm2. While plated at 8×102/cm2, the number of the cells was only expanded (5±3) times. Proliferative ability of cells cultured at a low density was stronger that that at a high density. MSCs could be induced to differentiate into the osteocytic lineages after plated at not only 8×103/cm2 but also 8×102/cm2.CONCLUSION: Cell density plays an evident role in the proliferation of MSCs. Cell density of 8×103/cm2 is proper to the rapid proliferation of MSCs as seed cells in bone tissue engineering.

Objective To observe the biological behavior of chondrocytes in chitosan based hydrogel in vitro and to evaluate the possibility of chitosan and glycerophosphate mixed gel using as injectable scaffolds in tissue engineering.Methods A novel injectable thermosetting gel was made of chitosan and glycerophosphate mixture.Chondrocytes isolated by enzymic digestion from the articular cartilage of the young rabbits aged 3-4 weeks were cultured in monolayer system.After primary culture and subculturing,the cells were seeded in chitosan based gel in concentration of 5?10~7/ml in vitro.Characteristics of chondrocytes during 4-week culture were observed with invert microscope.MTT was used to detect the seed growth after one-week culture.In 4th week,after haematoxylin eosine and toluidine blue staining,the artifical cartilage was performed type Ⅱ collagen immunohistochemistry and observed by scanning electron microscope.Results Chondrocytes retained their round morphology,multiplied,and produced matrix in chitosan and glycerophosphate mixture gels.The results of immunohistochemistry were strongly positive.Conclusion That most chondrocytes appeared to occupy large areas of rough chitosan based gels,guarantees a suitable environment where chondrocytes secrete matrix macromolecules and preserve their round morphology in vitro.Chitosan and glycerophosphate mixture gel may be a vehicle for injectable tissue-engineered cartilage.

AIM:To investigate the effect of Xingnaojing (XNJ) injection on the permeability of blood-brain barrier ( BBB) and zonula occludens-1 ( ZO-1) protein expression after global ischemia-reperfusion in rats.METHODS:Improved Pulsinelli four-vessel occlusion method was adopted to establish the global ischemia-reperfusion model in the rats. Male Wistar rats were randomly divided into sham group, model group, solvent group and XNJ group.The observations were conducted at the time points of 24 h, 48 h and 72 h after ischemia reperfusion.The water content of the brain tissues was determined by dry-wet weight method, while the Evans blue ( EB) content of brain tissue was detected by spectropho-tometry.The protein levels of ZO-1 in the cerebral cortex were analyzed by Western blot.RESULTS:The water contents in the brain tissues in model group, solvent group and XNJ group were significantly higher than those in sham group ( P<0.05) 24 h after ischemia reperfusion.However, the brain water contents in model group and solvent group were signifi-cantly higher than those in XNJ group and sham group (P<0.05) 48 h and 72 h after ischemia reperfusion.The EB con-tents in the brain tissues in model group, solvent group and XNJ group were entirely higher than that in sham group 24 h af-ter ischemia reperfusion (P<0.05).The EB contents in sham group and XNJ group were significantly lower than those in model group and solvent group 48 h and 72 h after ischemia reperfusion (P<0.05).The protein expression of ZO-1 in the rat cerebral cortex in model group, solvent group and XNJ group was significantly lower than that in sham group 24 h after ischemia-reperfusion (P<0.05).Similarly, 48 h and 72 h after ischemia reperfusion, ZO-1 protein level in the cortex in sham group and XNJ group was significantly higher than that in model group and solvent group (P<0.05).CONCLU-SION:At 48 h and 72 h after global ischemia-reperfusion, Xingnaojing injection play a protective role in blood-brain barri-er and this role may be associated with the increase in ZO-1 protein expression by Xingnaojing injection.
