Article Title: Ocimum flavone Orientin as a countermeasure for thrombocytopenia

doi: 10.1038/s41598-018-23419-x

Figure Lengend Snippet: Effect of Orientin on human hematopoietic stem cells. ( a – c ) Orientin induces human CD34 + cells differentiation towards MEP lineage. CD34 + cells purified from healthy donor’s PBMCs via density gradient ficol followed by magnetic bead separation were treated with or without Orientin in a serum free expansion medium (SFEM) supplemented with 100 ng/ml cytokine cocktail (CC100) for 7 days. Cells were harvested for lineage differentiation and stained with CD34-PE-Cy7, CD38-Pacblue, CD10-FITC, CD135-PE, CD45RA-APC antibodies and subjected to FACS analysis. (d) Orientin partially restores CD34 + cells differentiation potential after irradiation. CD34 + cells purified from healthy donor’s PBMCs (1 × 10 5 /ml in triplicates) were treated with or without Orientin (5 µM) and exposed to 4 Gy (fractionated dose of 2 × 2 Gy). These cells were then co-cultured on human mesenchymal stromal cell layer in SFEM medium supplemented with 100 ng/ml cytokine cocktail for normal differentiation in 7 day time period. The MEP cells were gated in lin − CD34 + CD38 + CD10 − CD135 − CD45RA − block in each sample. ( e ) Colony Assay in CD34 + cells (1 × 10 3 /ml in triplicates) post 0 or 2 Gy X-ray exposure. CFU-GM and GEMM colonies were scored on day 14 by applying standard morphologic criteria.

Article Snippet: CD34 + cells were purified from PBMCs using Diamond CD34 isolation kit for human (#130-094-531, MiltenyiBiotec) as described by manufacturer.

Article Title: Spred1 deficit promotes treatment resistance and transformation of chronic phase CML

doi: 10.1038/s41375-021-01423-x

Figure Lengend Snippet: A Expression of SPRED1 in BM CD34+ cells from patients with BC CML and CP CML by Q-RT-PCR (n=8 samples for BC CML and n=12 samples for CP CML) and western blot and in BM by immunohistochemistry staining (one of three independent experiments with similar results was shown) (left), and expression of miR-126 in CD34+ and CD34+CD38− cells from BC CML (n=6 samples) and CP CML (n=10 samples) patients by Q-RT-PCR (right). B SPRED1 mRNA expression by Q-RT-PCR and protein expression by western blot, miR-126 levels by Q-RT-PCR, cell cycling by Ki-67 and DAPi staining (top) or by cell trace violet staining (bottom) followed by flow cytometry analysis in CML CD34+ cells transduced with SPRED1 siRNA to knock-down (KD) SPRED1 or with a non-targeting control siRNA (Ctrl). UND: undivided cells, G0; DIV: division. C Representative colonies and quantification of colony forming cells (CFC) in CML CD34+ (left) and CD34+CD38− (right) cells transduced with Spred1 siRNA to KD SPRED1 or with ctrl siRNA (n=3). Results shown represent mean ± SEM. Significance values: *, p<0.05; **, p<0.01; ***, p<0.001.

Article Snippet: Human CD34 + cells were selected using the indirect CD34 microbead kit (Miltenyi Biotec, San Diego, CA) and CD34 + CD38 − cells were sorted after staining with human antibodies against CD34 and CD38 ( Supplementary Table 1 ) or selected using CD34+CD38- cell isolation kit (Miltenyi Biotec, San Diego, CA) according to the manufacturer’s protocol.

Article Title: In Vivo Serial MR Imaging of Magnetically Labeled Endothelial Progenitor Cells Homing to the Endothelium Injured Artery in Mice

doi: 10.1371/journal.pone.0020790

Figure Lengend Snippet: 7 days after in vitro differentiation, spleen-derived EPCs showed expression of CD31 (B), CD34 (C) and vWF (D) with the cytoplasm stained in brown. Photo A is the control. Hematoxylin-stained nuclei were shown in blue. (Magnification ×400).

Article Snippet: After 7 days in culture, spleen-derived EPCs in 4 wells of a 24-well culture plate were extensively washed, and fixed in ice-cold 4% paraformaldehyde for 20 min. Immunocytochemistry was performed using antibodies against CD31, CD34 (Wuhan Boster Biological Technology, LTD. Wuhan, China) and von Willebrand factor (vWF) ( Zhongshan Goldenbridge Biotechnology Co., LTD. Beijing, China) according to standard protocols.
