Coculture experiments were performed with a mixture of 5 × 103 MSCs and 5 × 102 CD34+ HSPCs per well in 40 μL medium consisting of GMP and serum-free expansion medium (SFEM; Stem Cell Technologies, Grenoble, France) at a 1 : 4 ratio supplemented with the recombinant human cytokines Flt-3 ligand, stem cell factor (100 ng/mL each), interleukin-3, and interleukin-6 (20 ng/mL each) (CC100; Stem Cell Technologies), from here on referred to as “GMP-SFEM-CC100 medium.” Cells were kept in a fully humidified atmosphere with 5% CO2 at 37°C. A partial medium exchange was performed every 2 to 3 days.
Cc100
The CC100 is a multi-purpose centrifuge that can be used for a variety of laboratory applications. It features an adjustable speed range and a versatile rotor that can accommodate different types of sample tubes or plates. The CC100 provides consistent and reliable performance to meet the needs of various research and testing workflows.

were purchased from ATCC. Cells were cultured in Iscove’s modified
Dulbecco’s medium containing 10% (v/v) fetal bovine serum and
5% penicillin and streptomycin, as previously described.53 (link) All cultures were grown at 37 °C in a humidified
environment containing 5% CO2.
CD34+ cells
were expanded in H3000 media supplemented with CC100 (Stem Cell Technologies)
for 4 days at a density of 105 cells/mL prior to use for
compound evaluation. Cells were treated for 24, 48, or 72 h with an
appropriate concentration of each analogue.

Erythroid Differentiation of CD34+ HSPCs
After the maintenance phase, CD34+ HSPCs were differentiated using the three-phase culture system previously described.63 (link),64 (link) First, a base erythroid medium was created by supplementing IMDM with 2% human AB plasma, 3% human AB serum, 3 U/mL heparin, 10 μg/mL insulin, 200 μg/mL holo-transferrin, and 1% penicillin/streptomycin. From days 1-7 in erythroid media, this base medium was further supplemented with 3 U/mL EPO, 10 ng/mL human SCF, and 1 ng/mL IL-3. From days 7-12, this base medium was further supplemented with 3 U/mL EPO and 10 ng/mL human SCF. After day 12, the base medium was supplemented with 1 mg/mL total of holo-transferrin and 3 U/mL of EPO.

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.
