    • 摘要: 目的 比较组织块法与酶消化法对分离培养人脐带间充质干细胞(hUC-MSCs)的影响.方法 选取5根足月妊娠自然分娩的健康婴儿的废弃脐带,采用组织块法和酶消化法进行原代分离培养,比较两种培养方法的细胞增殖情况,并测定其细胞表面免疫标志物.结果 hUC-MSCs的融合状况:组织块法培养的第5天,细胞从组织块内爬出,培养2周左右细胞融合率可达80% 以上;酶消化法培养5 d后,可见少量形态不规则的细胞贴壁,培养2周后细胞融合可达40% ~50%.hUC-MSCs的增殖情况:组织块法原代及传代后的hUC-MSCs的增殖速度远高于酶消化法,差异有统计学意义(P95%;酶消化法分离培养的P3细胞表面CD34、CD45、HLA-DR、CD105表达95%.结论 组织块法与酶消化法相比,能获得较纯的hUC-MSCs,且方法简单、成本低,是获得hUC-MSCs的理想方法.

    • 摘要: 背景:胎盘间充质干细胞能够为细胞治疗提供理想的种子细胞,但其培养未曾使用过胰酶冷消化法,故对此方法进行探索,并与组织块法进行比较,从中筛选出一种方便易行、培养成功率更高的方法.目的:观察胰酶冷消化法与组织块法分离培养的人胎盘间充质干细胞的生物学特性.方法:采用胰酶冷消化法和组织块法从人胎盘中分离、纯化和传代培养人胎盘间充质干细胞(n=6).记录胎盘间充质干细胞首次出现时间及原代培养周期,绘制第3代细胞生长曲线,流式细胞仪分析第3代细胞表面标志,检测其向成神经及成脂方向诱导分化能力.结果与结论:①使用上述2种培养方法均可获得胎盘间充质干细胞,胰酶冷消化法首次出现贴壁细胞时间早于组织块法(P < 0.05),原代培养周期短于组织块法(P< 0.05);②生长曲线提示在进入平台期后的各个时间点胰酶冷消化法培养的细胞数量明显多于组织块法(P<0.05);③2种细胞具有均一的细胞表型,均表达CD29,CD105,不表达CD34,CD45;④2种方法培养的胎盘间充质干细胞经诱导后均具有成神经及成脂分化潜能;⑤上述结果表明,对于胎盘间充质干细胞的培养而言,胰酶冷消化法具有明显优势.

    • 摘要: 背景:关于人胎盘绒毛膜间充质干细胞分离培养方法的研究很多,但是如何简便、快捷获得大量原代培养间充质干细胞的问题尚未解决.目的:探讨优化人胎盘绒毛膜间充质干细胞体外分离培养组织块法的最佳方法.方法:无菌条件下,取正常足月剖宫产胎盘绒毛膜,用匀浆器处理组织块,采用组织块法贴壁分离培养人胎盘绒毛膜间充质干细胞,经初次培养的组织块进行再次接种培养.结果与结论:用电动匀浆器处理人胎盘绒毛膜省时省力,组织分散度和去除红细胞效果好.初次培养和再次培养获得细胞的平均时间分别为(17.73±1.14)d和(10.03±1.30)d.每个Φ100 mm培养皿获得的原代细胞分别为(6.97±0.98)×105个和(13.82±1.44)×105个.获得的贴壁细胞呈典型的成纤维细胞形态,呈平行或漩涡状生长,高表达CD90、CD73、CD105,而CD45、CD34、CD14、CD19、HLA-DR为阴性.细胞可向成骨、成脂方向诱导分化.结果表明优化的方法能够简便、快捷地处理人胎盘绒毛膜组织,获得大量的原代间充质干细胞.%BACKGROUND:There are a lot of studies on isolation and culture methods of human placental chorionic-derived mesenchymal stem cells (hpcMSCs), but how to simply and efficiently harvest a large amount of primary MSCs has not been resolved. OBJECTIVE:To optimize the tissue explants method of isolating and culturing hpcMSCsin vitro. METHODS:Human placental chorionic villi were collected from full-term deliveries under aseptic condition and isolated by electric homogenizer. hpcMSCs were prepared by tissue explants method. The fluid and tissue of the primary culture flask and douching normal saline of the initial culture were centrifuged and prepared for secondary culture. RESULTS AND CONCLUSION: It saved time and effort to treat human placental chorionic villi with electric homogenizer, with good effects on tissue dispersion and removal of red blood cells. The average time of cell acquisition in initial culture and secondary culture was (17.73±1.14) and (10.03±1.30) days, respectively. The yields of primary cultured cells in initial culture and secondary culture were (6.97±0.98)×105 and (13.82±1.44)×105per Φ100 mm culture dish, respectively. The adherent cells showed fibroblast-cell-like shape, which were in parallel or circinate arrangement. Highly expressed CD73, CD105 and CD90 could be detected in the third generation of hpcMSCs, but CD34, CD45, CD14, CD19 and HLA-DR were negative. Following induction, alizarin red staining and oil red O staining produced a strong reaction in cells. In a word, the optimized method is a simple and efficient method for obtaining a large amount of primary hpcMSCs.

OBJECTIVE:To explore a simple and effective culturing method of primary osteoblasts. METHODS:Osteoblasts were isolated from the parietal and frontal bones of newborn Sprague-Dawley rats using trypsin and collagenase digestion and tissue explant method. The morphology of osteoblasts was observed by inverted phase contrast microscope and transmission electron microscope;the cells was counted to draw the growth curve;the osteoblasts were identified by alkaline phosphatase BCIP/NBT staining and alizarin red staining. RESULTS AND CONCLUSION:The cells showed spindle, triangle or polygon shapes, having two or three protrusions. There were abundant mitochondria and endoplasmic reticulum under electron microscope, which presented the typical characteristics of osteoblasts. The cell growth was slow intially, accelerating at the 3rd day, and peaking at the 7th day. The cells were highly positive for alkaline phosphatase staining and were stained orangered through the alizarin red staining. To conclude, the cells isolated using enzymatic digestion combined with tissue explant method exhibit the typical characteristics and functions of osteoblasts, and this method is an ideal way to culture primary osteoblasts.
