Quantification of Circulating CD34+ Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
After 12-h of fasting, 3 mL of heparinized peripheral blood were obtained and CD34+ cells were measured. The precise number of circulating CD34+ cells was quantified as we described previously7 (link). We evaluated circulating CD34+ cells with a Stem-Kit™ (BeckmanCoulter, Marseille, France) according to the manufacturers’ protocols. These protocols are based on International Society of Hematotherapy and Graft Engineering (ISHAGE) Guidelines8 (link), and are frequently used for quantification of CD34+ cells mobilized into the peripheral blood. To increase the reproducibility of CD34+ cell counts, the protocol of the Stem-Kit was modified as follows: the blood sample volume, antibodies and lysing solution were doubled. After adding 30 μL of internal control (Stem count: BeckmanCoulter), samples were centrifuged for 5 min at 450 g, and 3,860 μL of supernatant was removed carefully with a pipet. Samples were analyzed by Coulter CYTOMICS™ FC500 and XL-system II software (BeckmanCoulter) for 6 min each.

Apoptosis Detection via Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
Surface exposure of phosphatidylserine on apoptotic cells was measured by flow cytometry with a Coulter Cytomics FC500 (Beckman Coulter) by adding Annexin V conjugated to fluorescein isothiocyanate (FITC) to cells according to the manufacturer's instructions (Annexin V Fluos, Roche Diagnostic). Simultaneously, the cells were stained with PI. Excitation was set at 488 nm, and the emission filters were at 525 and 585 nm, respectively, for FITC and PI.

The analysis of the mitochondrial potential was carried out by flow cytometric analysis. Briefly, the cells treated with the test compound were labeled with the JC-1 dye as previously described [53 (link)]. The labeled cells were analyzed using the Coulter Cytomics FC500 (Beckman Coulter) in the FL1 and FL2 channel, respectively.

The quantification of the apoptosis induced by the test compounds was carried out by flow cytometric analysis using the Annexin-V Fluos kit (Roche Diagnostics, Rotkreuz, Switzerland) following the manufacturer’s instructions. The HeLa cells treated with the test compounds for different incubation times and at the indicated concentrations were then labeled with annexin V/FITC and PI and analyzed with Coulter Cytomics FC500 (Beckman Coulter) in the FL1 and FL3 channel, respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
