概述

使用StemSpan™淋系祖细胞扩增添加物（10X），可选择性促进从人脐带血（CB）样本中分离的CD34+细胞扩增并分化为CD7+CD5+ T祖细胞（pro-T细胞）。

该添加物是StemSpan™ T细胞生成试剂盒或STEMdiff™ T细胞分化试剂盒的组分之一，也可单独购买，需搭配StemSpan™ SFEM II培养基以及用StemSpan™淋系分化包板材料（100X）包被的培养板使用。如需将T祖细胞进一步成熟为CD4+CD8+双阳性（DP）T细胞，可使用StemSpan™ T细胞祖细胞成熟添加物（10X）。

关于使用StemSpan™进行CD34+细胞扩增与分化的详细实验方法，请参阅技术手册与教育资源。

Data Figures

Figure 1. Frequency and Yield of CD7+CD5+ Pro-T Cells After 14 Days of Culture

CB-derived CD34+ cells (freshly isolated or frozen) were cultured for 14 days in StemSpan™ SFEM II containing Lymphoid Progenitor Expansion Supplement (Catalog #09915) on plates coated with Lymphoid Differentiation Coating Material (Catalog #09925). Cells were harvested and analyzed for CD7 and CD5 expression by (A) flow cytometry. The (B) average frequency of viable CD7+CD5+ pro-T cells on day 14 was 70%, with ~200 CD7+CD5+ cells produced per input CD34+ cell. Shown are means with 95% confidence intervals (n = 33).

Figure 2. Frequency and Yield of CD4 ISP and CD4+CD8+ DP Cells After 42 Days of Culture

CB-derived CD34+ cells (freshly isolated or frozen) were cultured with the StemSpan™ T Cell Generation Kit (Catalog #09940) for 42 days and (A) analysed by flow cytometry for the expression of CD4, CD8, CD3 and TCRαβ. The (B) frequency and (C) yield of CD4 ISP, double-positive (CD4+CD8+) and CD3+TCRαβ+-expressing double-positive cells (CD4+CD8+CD3+TCRαβ+) are shown. On average, 38% of the total viable population were DP (CD4+CD8+), of which 35% co-expressed CD3 and TCRαβ. The yields of total DP cells and CD3+TCRαβ+ DP cells per input CD34+ cell were ~23,000 and ~9,000, respectively. Shown are means with 95% confidence intervals (n = 31).

Figure 3. Frequency and Yield of CD8 SP T Cells After 49 Days of Culture

DP cells were further matured into CD8 SP T cells by culturing for an additional 7 days in StemSpan™ SFEM II with T Cell Progenitor Maturation Supplement (Catalog #09930), IL-15 (Catalog #78031) and ImmunoCult™ CD3/CD28/CD2 T Cell Activator (Catalog #10970) on coated plates. On day 49, cells were (A) analyzed by flow cytometry for the expression of CD3, TCRαβ, CD4 and CD8. The (B) frequency and yield of CD3+TCRαβ+-expressing cells and their subsets are shown. On average, 54% of the CD3+TCRαβ+ cells were DP (CD4+CD8+) and 38% were CD8 SP (CD4-CD8+). The average yield of CD8 SP T cells per input CD34+ cell was ~6,000. CD3+TCRαβ+ CD4 SP (CD4+CD8-) T cells were detected at very low frequencies (data not shown). Shown are means with 95% confidence intervals (n = 12).
