Regenerative medicine for BRain and nerve repair

We isolated and propagated neural stem cells from the exposed BRain tissue of the patients with open BRain trauma, and then implanted neural stem cells with MRI-guided stereotactic device for the patients. Within 2-years follow-ups, the patients were investigated for functional recovery. Contrast to the case control group, implantation of neural stem cells was associated with a significant improvement in patient's neurological function. Investigations of stem cell therapy have required analysis of the fate and migration of implanted neural stem cells. Here, We demonstrate the feasibility of labeling human neural stem cells and retinal stem cells with nanoparticle and tracking of implanted cells in monkey and human central nervous system (CNS). This data demonstrates the possibility of stem cell therapy in CNS and collectively provide necessary foundation for overcoming challenges to the enhancement of translational regenerative medicine of BRain and optic nerve injury.

金颖:Fox3 suppresses NFAT-mediated differentiation to maintain self-renewal of emBRyonic stem cells

金颖教授为分子发育生物学研究室主任,健康科学中心研究员。金教授介绍了Fox3通过抑制NFAT介导的分化维持了胚胎干细胞的自我更新的机制等前沿发现。<BR><BR>Pluripotency-associated transcription factor Foxd3 is required for maintaining pluripotent cells. However, molecular mechanisms underlying its function are largely unknown. <BR><BR>Here, we report that Foxd3 suppresses differentiation induced by Calcineurin-NFAT signaling to maintain the ESC identity. Mechanistically, Foxd3 interacts with NFAT proteins and recruits co-repressor Tle4, a member of the Tle suppressor family highly expressed in undifferentiated ESCs, to repress NFATc3’s transcriptional activities. <BR><BR>Furthermore, global transcriptome analysis shows that Foxd3 and NFATc3 co-regulate a set of differentiation-associated genes in ESCs. Collectively, our study establishes a molecular and functional link between a pluripotency-associated factor and an important ESC differentiation-inducing pathway.

告别BRadford法,全球首台红外光谱仪,检测蛋白含量

Direct DetectTM是全球第一台基于红外原理的生物分子样本定量分析系统,只需要2微升样本以及空白对照(Blank),就可以直接获取结果。无需样本准备,无需比色杯,绝无废液。 Direct DetectTM系统直接基于蛋白长链中的氨基区域在红外吸收光谱分析,无需考虑氨基酸的组成、染料性质、氧化还原电位这些因素,避免了比色法分析的缺陷,可以获得更加准确的结果。 蛋白、脂肪、碳水化合物以及核酸都有可被区分的特定红外吸收光谱,所以您可以很轻松实现复杂混合物各种组分浓度的准确分析。
