Abstract: We describe a new two-step culture method for mass production in vitro of erythroid cells from either CD34+ (105 cells/mL) or light-density (106 cells/mL) cells purified from the blood of normal donors and thalassemic patients. The method includes (i) culture of the cells in the presence of dexamethasone and estradiol (10?6 M each) and (ii) the growth factors SCF (50 ng/mL), IL-3 (1 ng/mL), and EPO (1 U/mL). In their proliferative phase, these cultures generated about 1-2×107 erythroblasts for each milliliter of blood collected from normal donors or thalassemic patients. They were composed mostly (90%) of CD45low/glycophorin (GPA)neg/CD71low cells at day 7, 50-60% of which became CD45neg/GPA+/CD71high by days 15-20. However, when cells from days 7 to 12 of the proliferative phase were transferred in differentiation medium containing EPO and insulin, they progressed to mature erythroblasts (>90% benzidinepos and CD45neg/GPA+/CD71medium) in 4 days.

Abstract: A patient replica is created from layered culture medium where solid culture medium is formed so that a discontinuity exists, for example, between layers of culture medium or between culture medium and the container holding the medium. An injection port is provided in registration with the discontinuity so that a sample of patient blood can be infused into the discontinuity to form a thin layer of blood in contact with a surface of culture medium. The thin layer of blood obviates the requirement for any anticoagulant allowing blood-borne pathogens to be readily cultured without using broth. Further antibiotics or other drug samples may be placed on an exposed surface of the culture medium above the blood layer so that the antibiotic can diffuse through the culture medium and reveal the sensitivities of the cultured pathogens.
