    STEM-CELLBANKER®
    GMP grade

    Preserving cells, tissues & organoids for regenerative medicine and cell therapy research

    Product Basics

    STEM-CELLBANKER® GMP grade is a chemically defined freezing solution with an optimized formulation for the storage of stem cells, iPS cells, and other valuable cells. Recent data also support its effectiveness for tissue cryopreservation. It is entirely free of serum and animal-derived components, containing only ingredients graded USP, EP, or JP. It’s a ready-to-use solution with a simple protocol that promises a safe and effective cryopreservation of stem cells and iPS cells.

    STEM-CELLBANKER® GMP grade is manufactured in compliance with JPN, EU, US, and PIC/S GMP guidelines.

    Technical Information

    Cryopreservation analysis on hESC and iPS cells with STEM-CELLBANKER

    By Department of Clinical Science, Intervention and Technology, Karolinska Institute

    Cryopreservation analysis

    Tested cell lines: HS293 & HS306 (hESC); ChiPSA (human iPS)
    Freezing medium: STEM-CELLBANKER® vs Conventional freezing medium (10% DMSO in serum replacement containing culture medium)
    Cell viability assessment: trypan Blue & calcein-esterase based live-dead assay

    Result: Significantly higher cell viability was observed while cell pluripotency, normal karyotype, and proliferation ability were maintained in HS293, HS306 and ChiPSA cell lines.

    Special thanks to Prof. Outi Hovatta and Ms. Frida Holm for above analysis.

    Cryopreservation analysis on Mesenchymal Stem Cells (MSCs) and Endothelial Progenitor Cells (EPCs) with STEM-CELLBANKER®

    By Regenerative Medicine Faculty, University of Tsukuba

    MSCs EPCs
    STEM-CELLBANKER® >95% >90%

    Tested cell lines: Human UCB-derived MSCs and EPCs
    Freezing medium: STEM-CELLBANKER®
    Freezing protocol: Cell froze directly at -80℃ for 3 days, transfer to -192℃ for 72 days.
    Cell viability assessment: trypan Blue staining method.

    Result: Cell viability as high as or more than 95% for MSCs and 90% for EPCs was observed while cell proliferation ability and differentiation ability were maintained in tested cells.

    Special thanks to Prof. Osamu Ohneda and Dr. Masumi Nagano for above analysis.

    Active caspase 3 staining

    Mouse kidney was minced into about 5 mm square. The tissue samples were either immediately fixed with 10% formalin or cryopreserved with 1 ml of STEM-CELLBANKER at -80°C for one week. The cryopreserved samples were fixed with 10% formalin immediately after thawing. Paraffin sections of both samples were stained with either H&E or anti-active caspase 3 antibody. Sign of necrosis or apoptosis was negligible in both fresh and cryopreserved tissue samples. Similar results were obtained from tissue samples from a variety of mouse organs.

    Cryopreservation of mouse kidney tissue using STEM-CELLBANKER®

    Total RNA was extracted from the cells of a mouse lung fibroblast cell line either immediately after harvesting or after cryopreservation with STEM-CELLBANKER at -80°C for one week and thawing. mRNA levels in the two samples were compared DNA microarray analysis, and the results showed that 93% of mRNAs was within the range of + 1.6-fold difference.

    Protocol

    Freezing

    For optimum results, cells for cryopreservation should be in log phase of growth. Similar or other standard freezing protocols may be substituted.

    1. Examine and make sure the cell culture is free of contamination, in healthy and at proper confluency.
    2. Perform a cell count to determine the viability of cells.
    3. Centrifuge at 1,000 – 2,000 rpm, 4°C for 3 to 5 minutes to gently pellet the cells. Remove the supernatant with an aspirator.
    4. Gently suspend STEM-CELLBANKER® GMP grade cryopreservation medium (1 mL for 5×10⁵ – 5×10⁶ cells).
    5. Transfer 1 mL of the cell suspension to cryopreservation vial labeled with appropriate information (the cell line name, concentration, passage date etc.).
    6. Place the vials directly in -80℃ for storage.
    7. (OPTIONAL) Transfer the frozen vials to a liquid nitrogen storage tank after the vials have been frozen for at least 24 hours.

    IMPORTANT: Optimum protocol may change with the cell types.

    Thawing

    1. Remove the cryopreservation vial from the freezer and quickly thaw cells in a 37°C shaking water bath or shake by hand.
    2. Transfer the content to a centrifugation tube then immediately dilute and gently mix with 10mL of complete cell culture medium. Using CELLOTION® instead of complete culture medium will prevent adhesion of cells to the wall of the tube, increasing the recovery rate.
    3. Centrifuge cells at 1,000 – 2,000 rpm, 4°C for 3 to 5 minutes. Remove the supernatant with an aspirator.
    4. Gently resuspend the cells with an appropriate volume of complete cell culture medium then plate in a culture flask or plate
    5. Continue the culture procedures according to standard protocols.
