BACKGROUND: Studies have demonstrated that trehalose possesses protective effects on cyropreserved sternum. But the mechanism of action remains poorly understood. OBJECTIVE: To investigate the effects of trehalose on bcl-2 and bax mRNA expression in cryopreserved sternum. METHODS: Four groups of freshly prepared solution were used: low-potassium dextran (LPD), LPD + dimethyl sulfoxide (DMSO), LPD + trehalose, LPD + DMSO + trehalose. Rat sternum was cut and then immediately cryopreserved in the tubes containing each group of solution. Fresh rat sternum tissue and 4 groups of samples cryopreserved for 120 days were taken and bcl-2 and bax mRNA expression in fresh and cryopreserved sternum was detected using reverse transcription-polymerase chain reaction.RESULTS AND CONCLUSION: bcl-2 mRNA expression in the LPD + trehalose group was significantly higher, but bax mRNA expression was significantly lower, than in the LPD, LPD + DMSO groups (both P < 0.01). LPD + DMSO + trehalose group showed highest bcl-2 mRNA expression and lowest bax mRNA expression, which were basically similar to fresh bone tissue (P > 0.05). These findings indicate that trehalose may protect cell activity in cryopreserved sternum by enhancing bcl-2 mRNA expression and inhibiting bax mRNA expression, and trehalose together with DMSO shows better protective effects.

Objective To investigate the effect on the differentiation of bone marrow mesenchymal stem cells (BMSC) with non-contact co-culture with mechanical stimulated ligament fibroblasts. Methods A cyclic 10% uniaxia strain at 1 Hz was applied on rat pelvic ligament fibroblasts, then were co-cultured with BMSC for 3, 6 and 12 days in non-contact condition. The protein expression of collagen Ⅰ ,Ⅲ in BMSC were detected by SP method and revealed by the mean gray value. The mRNA expressions of collagens type Ⅰ and type Ⅲ in the BMSCs were measured with real-time (RT)-PCR ,and the results were indicated by the ratio between the mRNA and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) . Results (1) Protein expression; after 3 days co-culture with pelvic ligament fibroblasts, expression of collagen Ⅰ and Ⅲ in BMSC are 82. 4 ± 3. 4 and 76. 8 ± 2. 5. When compared with 80. 2 ± 2. 6 and 74. 6 ± 1. 1 in BMSC without co-culture, there was no significant difference (P > 0. 05) . After 6 days co-culture with pelvic ligament fibroblasts, the expression of collagen Ⅰ and Ⅲ of 126. 6 ±2. 2 and 118. 6 ± 1. 4 in BMSC were significantly higher than 82. 7 ±3. 0 and 76. 2 ± 1. 3 in BMSC without co-culture (P < 0. 05). Similarly, after 12 days co-culture with pelvic ligament fibroblasts, the expression of collagen Ⅰ and Ⅲ of 135. 3 ±3. 4 and 128. 7 ± 2. 6 in BMSC were significantly higher than 86. 6 ± 1. 3 and 81. 8 ± 1.4 in BMSC without co-culture (P <0.05). (2)mRNA expression:after 3 days co-culture with pelvic ligament fibroblasts , the mRNA expression of type Ⅰ and type Ⅲ collagens in BMSC are 2. 10 ±0. 20 and 1. 20 ±0. 30. When compared with mRNA expression of 2. 01 ±0. 12 and 1. 13 ±0.21 in BMSC without co-culture, no significant difference were observed (P > 0. 05). After 6 days co-culture with pelvic ligament fibroblasts , the mRNA expressions of type Ⅰ and type Ⅲ collagens mRNA were 5. 60 ±0. 21 and 2. 61 ±0. 20, which were significantly higher than 3. 70 ±0. 33 and 1. 82 ± 0. 14 in BMSC without coculture (P < 0. 05). After 12 days co-culture with pelvic ligament fibroblasts, the mRNA expressions of type Ⅰ and type Ⅲ collagens of 5. 91 ±0.31 and 2. 92 ±0. 23 were significantly higher than 4. 04 ±0. 21 and 2. 04 ±0. 13 in BMSC without co-culture (P <0. 05). Conclusion Non-contact co-culture with mechanical stretch stimulated ligament fibroblasts, it might promote synthesis of types Ⅰ and Ⅲ collagen in rat BMSCs and induced BMSC differentiated into pelvic ligament fibroblasts.
