Primary Bone Marrow CD34+ Cells, Normal, Human


Primary Bone Marrow CD34+ Cells, Normal, Human are hematopoietic pluripotent stem cells isolated by immunomagnetic positive selection. CD34+ bone marrow-derived and CD34+ cord blood-derived cells may be used to support physiologically relevant research in regenerative medicine, transplant studies, stem cell biology, hematology, and oncology.

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

All tissues used for isolation are obtained under informed consent and conform to HIPAA regulations to protect the privacy of the donor’s Personally Identifiable Information. It is best to use caution when handling any human cells. We recommend that all human cells be accorded the same level of biosafety consideration as cells known to carry Human immunodeficiency virus (HIV) and other bloodborne pathogens. With infectious virus assays or viral antigen assays, even a negative test result may not exclude the possibility of the existence of a latent viral genome or infectious viral particles below the lower limit of detection of that assay.

ATCC recommends that appropriate safety procedures be used when handling all primary cells and cell lines, especially those derived from human or other primate material. Handle as a potentially biohazardous material using universal precautions. Cells derived from primate lymphoid tissue may fall under the regulations of 29 CFR 1910.1030 Bloodborne Pathogens.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Growth properties
Suspension, variable after culturing

Cluster of differentiation 34 (CD34) is a sialomucin-family protein that is expressed on the surface of blood, endothelial, and bone marrow-derived progenitor cells. While the functions of CD34 are not well understood, there is evidence that the protein is involved in maintaining progenitor cells in an undifferentiated state.

The ATCC maintains CD34+ bone marrow-derived and CD34+ cord blood-derived cells which may be used to support physiologically relevant research in regenerative medicine, transplant studies, stem cell biology, hematology, and oncology. These pluripotent stem cells are isolated by immunomagnetic positive selection. In addition, the ATCC Cell Systems Laboratory has conducted in-depth characterization of the cells including differentiation into all three cell lineages.

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium
CD34+ cells have a limited lifespan in culture and should only be thawed immediately prior to their intended use. ATCC does not recommend maintaining CD34+ cells in culture in the absence of application-specific growth factors.
Handling procedure
  1. Rapidly thaw cryovial in a 37°C water bath.  Remove the vial before all the ice is thawed.
  2. Decontaminate the cryovial with ethanol and move it to a biosafety cabinet.
  3. While on ice, transfer contents of the vial to a 15 mL conical tube.
  4. Rinse the cryovial with 1 mL of ice-cold thawing media (Hank's Balanced Salt Solution without Ca2+ or Mg2+ (ATCC 30-2213), supplemented with  10% Fetal Bovine Serum (ATCC 30-2020) and slowly transfer to the cells in the conical tube.
  5. Slowly pipet 10X the vial volume of thawing media into the conical tube 
  6. Take a sample for counting and viability assessment. 
  7. Centrifuge the remaining contents of the vial at 4°C at 300 x g for 5 minutes to pellet cells.
  8. Aspirate the wash leaving a few mL behind.
  9. Re-suspend cells in the media of choice.
