使用无饲养层、无血清的 STEMdiff™ 单核细胞试剂盒,可将人多能干细胞(hPSCs)分化为表达 CD14 的单核细胞。

该简便的实验方案在二维贴壁培养中进行。在前 3 天,培养基 A 诱导细胞向中胚层分化。在接下来的 4 天,使用培养基 B 进一步诱导中胚层细胞向造血谱系分化。在第 7 天,将培养基更换为单核细胞分化培养基,以促进其向单核细胞分化。CD14 +单核细胞最早可从第 14 天开始从培养上清液中直接收集,并可在后续培养过程中多次收集。CD14 +细胞的峰值频率通常在 60% - 80%之间。

hPSC 衍生的单核细胞可分别使用ImmunoCult™ 树突状细胞培养试剂盒或ImmunoCult™-SF 巨噬细胞培养基进一步分化为树突状细胞或巨噬细胞。

为了方便起见,用于配制单核细胞分化培养基所需的成分StemSpan™ SFEM II和STEMdiff™ 单核细胞分化添加剂 (100X)也可单独购买。

Data Figures

Differentiation of hPSC-Derived CD34+ Cells into CD14+ Monocytes

Figure 1. Monocyte Differentiation Protocol

One day prior to differentiation, human pluripotent stem cell (hPSC) colonies are harvested and seeded as small aggregates (100 - 200 μm in diameter) at 10 - 20 aggregates/cm2 in mTeSR™1, TeSR™-E8™, or mTeSR™ Plus media. After one day, the medium is replaced with Medium A (STEMdiff™ Hematopoietic Basal Medium + Supplement A) to induce mesodermal specification (stage 1). On day 3, the medium is changed to Medium B (STEMdiff™ Hematopoietic Basal Medium + Supplement B) to promote hematopoietic specification (stage 2). On day 7, the medium is replaced with Monocyte Differentiation Medium (StemSpan™ SFEM II + STEMdiff™ Monocyte Differentiation Supplement) to promote the production of CD14+ monocytes (stage 3). Monocyte Differentiation Medium is used for all medium changes for the remaining culture period. CD14+ cells can be detected in suspension starting after day 14, and their frequency gradually increases until day 17 - 23. CD14+ cells can be harvested directly from the culture supernatant during medium changes.

hPSC-Derived CD14+ Monocyte Characterization, Frequency and Yield

Figure 2. Robust and Efficient Generation of CD14⁺ Monocytes Using STEMdiff™ Monocyte Kit

hPSCs were differentiated to monocytes using the 2D culture system described in Figure 1. Between days 17 and 23, cells were harvested every 2 - 3 days and analyzed by flow cytometry for CD14 expression. Representative flow cytometry plots are shown for (A, B) iPS (WLS-1C)-derived cells and (C, D) ES (H9)-derived cells. (E) The average frequency of viable CD14+ monocytes at the peak harvest was 61 - 78%. The average yield of CD14+ monocytes produced per 6-well plate at the peak harvest was between 1.6 x 10^6 and 7.1 x 10^6 cells. Data are shown as mean ± SEM (n = 3 - 14).

Characterization and Phagocytosis Analysis of Macrophages

Figure 3. STEMdiff™ Monocyte Kit Generates Monocytes That Are Capable of Differentiation to Macrophages

hPSC-derived monocytes were harvested after 21 days of culture. These were then differentiated to macrophages using ImmunoCult™-SF Macrophage Medium (Catalog #10961) with 100 ng/mL M-CSF for 4 days. Macrophages were then incubated for an additional 2 days with either 10 ng/mL of LPS and 50 ng/mL of IFN-γ, or 10 ng/mL IL-4, to become polarized to M1 or M2a macrophages, respectively. Representative flow cytometry plots of (A) M1 and (B) M2a macrophages produced from the WLS-1C iPS cell line are shown. (C) To measure phagocytosis, PSC-derived M2a macrophages and peripheral blood (PB) monocyte-derived M2a macrophages (primary M2a macrophages), were incubated with pHrodo™ Red Zymosan A BioParticles® Conjugate and incubated at 37°C for 8 hours. Images were acquired using the IncuCyte® ZOOM every 30 minutes and analyzed for internalization of pHrodo™ Red Zymosan A BioParticles® (measured as red object/mm2). hPSC-derived and primary M2a macrophages show similar phagocytic activity.

Characterization of Dendritic Cells

Figure 4. STEMdiff™ Monocyte Kit Generates Monocytes That Can Be Differentiated to Dendritic Cells

hPSCs were differentiated into monocytes, harvested after 21 days, and differentiated to dendritic cells using ImmunoCult™ Dendritic Cell Culture Kit (Catalog #10985). Half of the dendritic cells were harvested on day 7 and examined for CD14 and CD83 expression to identify CD14⁻CD83⁻/lo immature dendritic cells. The remaining dendritic cells were activated for 2 days and assessed for the presence of CD14⁻CD83⁺ mature dendritic cells at day 7. Representative cultures initiated with ES (H9) cells are shown for production of (A) immature dendritic cells and (B) mature dendritic cells.
