Human Mesenchymal Stem Cells - Bone Marrow (HMSC-BM)
General information
| Description | Human Mesenchymal Stem Cells derived from Bone Marrow (HMSC-BM) represent a robust and versatile tool for in vitro research. These multipotent mesenchymal stromal cells (MSCs) possess the unique ability to self-renew and differentiate into a broad spectrum of cell types, including adipocytes, osteoblasts, and chondrocytes. The potential of HMSC-BM to differentiate into these three key lineages has been well-documented, making them invaluable for studies focused on regenerative medicine, tissue engineering, and cellular differentiation pathways. These MSCs are cultivated under stringent conditions, ensuring their multipotency and high viability post-thaw. One of the distinguishing features of HMSC-BM compared to MSCs derived from other sources, such as adipose tissue or umbilical cord, is their superior capacity for osteogenic differentiation. This makes them particularly useful in bone biology and orthopedic research, where understanding the molecular mechanisms governing bone formation and repair is crucial. Additionally, HMSC-BM exhibit a robust immunomodulatory profile, which makes them an excellent model for studying immune interactions and inflammatory responses. These unique characteristics also position HMSC-BM as a preferred choice for preclinical studies exploring bone marrow microenvironment, hematopoiesis, and the pathophysiology of bone marrow-related diseases. Each cryovial of HMSC-BM contains a minimum of 1 x 106 cells, with viability rates ranging between 92% to 95%, as determined by the Trypan Blue dye exclusion test. These cells are derived from bone marrow collected from healthy adult donors, all of whom have provided informed consent. To ensure the highest standards, each batch undergoes rigorous quality control testing to assess cell identification, purity, potency, and viability. This thorough testing guarantees that the MSCs meet strict criteria, making them suitable for a wide range of research applications, including cell biology studies, drug discovery, and the investigation of cellular responses to different stimuli. These cells are not intended for therapeutic or in vivo applications, and their use is confined to research purposes in a controlled laboratory environment. |

Biomolecular Data
| Antigen expression | A comprehensive panel of markers, including CD73/CD90/CD105 (positive) and CD14/CD34/CD45/HLA-DR (negative), are used in flow cytometry analysis to identify cultivated MSCs (P2-P3) prior to cryopreservation. These markers are recommended by the ISCT MSC committee. |

Handling
| Culture Medium | Alpha MEM, w: 2.0 mM stable Glutamine, w/o: Ribonucleosides, w/o: Deoxyribonucleosides, w: 1.0 mM Sodium pyruvate, w: 2.2g/L NaHCO3 |
|---|---|
| Subculturing | For routine adherent cell culture: Aspirate the old culture medium from the adherent cells, and wash them with PBS to remove any remaining medium. After aspirating the PBS, add the appropriate volume of Trypsin/EDTA solution based on the culture vessel size (e.g., 1 ml for a T25 flask, 3 ml for a T75 flask) and incubate at room temperature or 37?C until the cells detach (5-10 minutes). Monitor detachment under a microscope, and gently tap the vessel if necessary to release the cells. Once detached, add complete medium to inactivate the Trypsin/EDTA, gently resuspend the cells, and transfer an aliquot of the cell suspension into a new culture vessel containing fresh medium. Place the vessel in an incubator set to 37?C with 5% CO2, and change the medium every 2-3 days. |
| Seeding density | 1 to 3 x 10^4 cells/cm^2 |
| Fluid renewal | First fluid renewal after 24 hours, then every 2 to 3 days. |
| Freeze medium | As a cryopreservation medium, use 80% FBS + 10% basal medium + 10% DMSO to maintain viability, or CM-1 (Cytion catalog number 800100) for superior cryoprotection, preventing unwanted differentiation while preserving pluripotency. |
Quality Control & Molecular Analysis
| Sterility | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
