培养基：CD CHO无血清培养基（摇床悬浮培养）
UM-Chor1 Human Mesangial Cells (human chordoma cells; STR authentication verified)
English Name: UM-Chor1 Human Mesangial Cells
Specifications: 1×10^6 cells/vial (cryovial, 1 mL/vial); or 1×10^6 cells/T25 flask (cultured after recovery)
UM-Chor1 Human Mesangial Cells is a normal cell line derived from human mesangium. These cells proliferate stably in vitro, showing growth in suspension, an epithelioid and polygonal morphology, and are widely used in research on cell biology, toxicological evaluation, and in vitro model construction. This product has passed STR profiling and matches the reference STR profile, with no cross-contamination, ensuring stable and reproducible experimental results.
Basic Information: Cell name: UM-Chor1 Human Mesangial Cells; Species: Human; Tissue source: Mesangium; Cell type: Mesangial cells; Growth characteristics: Suspension; Complete medium: CD CHO serum-free medium (shaker suspension culture); Culture conditions: 37°C, 5% CO2; Subculture ratio: 1:2–1:3; Cryopreservation: 90% FBS + 10% DMSO; Biosafety level: BSL-2
Product Advantages: ① STR profiling passed and consistent with the authoritative STR database, with no HeLa or other cross-contamination; ② Low passage number and high viability, with a post-thaw survival rate of ≥90% and stable adherence/proliferation; ③ Negative for mycoplasma, bacteria, and fungi, with no adventitious agent contamination; ④ Stable batches for long-term repeat supply, with a complete culture protocol; ⑤ Identification reports and batch quality inspection records available for traceability
After-Sales Service: Within 7 days of receiving the cells, if issues such as contamination, poor adherence, low viability, or failed authentication occur, free replacement or resupply will be provided after verification. Full technical support is available (medium preparation, recovery and subculture, cryopreservation, and experimental design advice), and STR/species identification reports, mycoplasma testing reports, and batch quality inspection records can be issued upon request.
Storage Conditions: Long-term storage in the gas phase of liquid nitrogen (-196°C); the -80°C freezer is suitable only for short-term storage (no more than 3 months). Avoid repeated freeze-thaw cycles; after removing the cryovial, thaw it rapidly in a 37-40°C water bath and transfer it to complete medium within 2 minutes.
Shipping Conditions: Cryovials are shipped on dry ice (maintained below -70°C throughout); T25 flasks are shipped at ambient temperature (filled with complete medium and sealed against leakage). Upon receipt, disinfect the surface with 75% ethanol and leave the cells in the incubator for 24 hours before observation and handling.
Species and Source: Species: Human; Tissue source: Mesangium; Species and tissue origin confirmed by STR profiling
Cell Morphology: Epithelioid and polygonal; adherent growth with a tightly packed monolayer arrangement
Growth Status: Suspension growth (shaker culture); density can exceed 1×10^6 cells/mL
Storage Life and Passage Limit: Long-term preservation under liquid nitrogen with a valid storage period of 5 years; after recovery, continuous passaging of no more than 10 passages is recommended (primary cells are recommended for use within 3-5 passages), as an excessively high passage number may cause phenotypic drift and reduced proliferative capacity.
Immunological Background: Human cells, with a xenotransplantation background; in vivo transplantation requires immunodeficient mice (e.g., BALB/c nude, NOD-SCID, NSG), while in vitro culture does not involve immune rejection; for immunological experiments, the compatibility between human MHC and the murine immune system should be considered.
Quality Control and Testing: STR profiling consistent with the reference standard (≥20 loci); mycoplasma testing negative; sterility testing negative for bacteria and fungi; cell viability ≥90%; endotoxin testing passed
Subculture Method: No trypsin digestion is required; directly transfer the cell suspension into fresh complete medium at a ratio of 1:2-1:3, or centrifuge at 1000 rpm for 5 minutes, discard the supernatant, resuspend, and inoculate; renew the medium every 2-3 days
Culture Conditions: Shaker culture at 37°C, 5% CO2, saturated humidity, 120-140 rpm; subculture every 2-3 days at a ratio of 1:3-1:5
Culture Medium: CD CHO serum-free medium (shaker suspension culture)
