使用无动物成分（ACF）的ImmunoCult™-ACF树突状细胞分化添加物，可从人单核细胞生成未成熟树突状细胞（DC）。

该产品作为ImmunoCult™树突状细胞培养试剂盒的组分，也可单独购买，以方便您的使用。将ImmunoCult™-ACF树突状细胞分化添加物与ImmunoCult™-ACF树突状细胞培养基搭配使用，可在体外生成未成熟DC；当与ImmunoCult™树突状细胞成熟添加物搭配使用时，可支持未成熟DC转化为成熟DC。

关于使用ImmunoCult™树突状细胞培养基进行培养和分化的详细方法，请参阅产品说明书（PIS）。

实验数据

Figure 1. Protocol Diagram.

Mature DCs were generated by culturing EasySep™ isolated monocytes at 1 x 10⁶ cells/mL in ImmunoCult™-ACF Dendritic Cell Medium (Catalog #10987) with added ImmunoCult™-ACF Dendritic Cell Differentiation Supplement (Catalog #10988). At day 3, the medium with differentiation supplement was replaced and cells were incubated for 2 more days. At day 5, without changing the medium, ImmunoCult™ Dendritic Cell Maturation Supplement (Catalog #10989) was added to the culture. At day 7, fully mature DCs were harvested for downstream applications.

Figure 2. Mature DCs generated with ImmunoCult™-ACF Dendritic Cell Medium with Supplements show desired phenotype.

EasySep™ isolated monocytes were cultured and differentiated into mature DCs as described in Figure 1. (A) The percentage of CD14 and CD83 expression in cells at day 7 (mature DCs) was determined by flow cytometry. At day 7, a total of 93 ± 5% of the cells expressed the mature DC marker CD83 and only 1 ± 1% of cells still expressed the monocyte marker CD14 (mean ± SD, n=39). Yield of mature DCs was determined by count of total viable cells at day 7 relative to the count of viable monocytes used for initial culture at day 0. At day 7, the yield of viable mature DCs corresponded to 45 ± 25% (mean ± SD, n=39). (B) Immature DCs were cultured as described in Figure 1. At day 5, cells were cultured with maturation supplement for 2 days (mature DCs) or without maturation supplement (immature DCs). Supernatant was collected at day 7 and IL-12p70 levels were determined by ELISA. Concentrations of IL-12p70 in supernatant of mature and immature DCs were 361 ± 81 and 5 ± 2 pg/mL, respectively (mean ± SEM, n=27).

Figure 3. Mature DCs generated with ImmunoCult™-ACF Dendritic Cell Medium and Supplements induce T cell proliferation.

Mature DCs generated with ImmunoCult™-ACF Dendritic Cell Medium and Supplements (ImmunoCult) or other serum-free competitor media (competitor 1 and 2) and corresponding supplements when applicable (competitor 2), were cultured in ImmunoCult™-XF T Cell Expansion Medium with 1 x 10⁵ CFSE labeled (A) allogeneic CD3+ T cells (MLR assay) or (B) autologous CD8+ T cells (antigen-specific T cell response). (A) Cells were cultured at a DC:T cell ratio of 1:25. (B) Prior to culture with T cells, immature DCs were loaded with HLA Class I peptides derived from the human Cytomegalovirus, Epstein-Barr Virus and Influenza Virus (CEF peptide pool) and stimulated with maturation supplement for 2 days. Cells were cultured at a DC:T cell ratio of 1:4 or 1:10. (A,B) CFSE labeled T cells were incubated in media alone (negative control) or with ImmunoCult™ Human CD3/CD28 T Cell Activator (positive control). After 5-7 days in culture the number of dividing T cells ( CD3⁺CFSE^lo) was assessed by flow cytometry (mean ± SEM) (A) n=5 (B) n=4 (competitor 1 and 2, n=3). Mature DCs generated in ImmunoCult™-ACF Dendritic Cell Medium induced proliferation of allogeneic and antigen-specific T cells similar to DCs generated in either competitor media. Competitors 1 and 2, include in no particular order, CellGro DC Medium (CellGenix) and PromoCell DC Generation Medium DXF.

Development of an iPSC-derived immunocompetent skin model for identification of skin sensitizing substances M. Dubau et al. Journal of Tissue Engineering 2025 May

Abstract

The development of immunocompetent skin models marks a significant advancement in in vitro methods for detecting skin sensitizers while adhering to the 3R principles,which aim to reduce,refine,and replace animal testing. This study introduces for the first time an advanced immunocompetent skin model constructed entirely from induced pluripotent stem cell (iPSC)-derived cell types,including fibroblasts (iPSC-FB),keratinocytes (iPSC-KC),and fully integrated dendritic cells (iPSC-DC). To evaluate the skin model’s capacity,the model was treated topically with a range of well-characterized skin sensitizers varying in potency. The results indicate that the iPSC-derived immunocompetent skin model successfully replicates the physiological responses of human skin,offering a robust and reliable alternative to animal models for skin sensitization testing,allowing detection of extreme and even weak sensitizers. By addressing critical aspects of immune activation and cytokine signaling,this model provides an ethical,comprehensive tool for regulatory toxicology and dermatological research.
