PRODUCT INTRODUCTION
Mesenchymal stem cells with RFP (MSCs/RFP) are multipotent stem cells that can
differentiate into a variety of cell types including osteocytes, adipocytes, and
chondrocytes. MSCs/RFP proliferate quickly and are capable of generating a local
immunosuppressive microenvironment, thus contributing to their wide application
potentials in tissue engineering, cell therapy, and gene therapy.
OriCellTM Sprague-Dawley (SD) Rat Mesenchymal Stem Cells are derived from the bone
marrow of Sprague-Dawley (SD) Rats, cultured as monolayer, and then have been
transfected with a lentiviral construct containing a RFP expression motif.
In addition, these cells have been tested for:
•
Exogenous Factors: bacterial/fungal contamination, mycoplasma contamination,
and endotoxin contamination.
•
Characteristics: post-thaw viability, cell cycle, verification of undifferentiated
state, and differentiation potential.
This product is intended for laboratory research use only. It is not intended for
diagnostic, therapeutic, clinical, household, or any other applications.

1. Pre-warm the OriCellTM MSC Growth Medium, 1×PBS, and 0.25%Trypsin-0.05%EDTA
solution to 37°C.
2. Carefully aspirate the spent medium from the 80-90% confluent monolayer of
MSCs/RFP.
3. Add 1×PBS (6 mL for T75 flask, 3 mL for T25 flask). Be careful not to disturb the
monolayer. Gently rock the flask back and forth to rinse the monolayer.
4. Aspirate 1×PBS off and discard.
5. Repeat steps 3-4 two or three times.
6. Add 0.25%Trypsin-0.05%EDTA solution (2-3 mL for T75 flask, 1 mL for T25 flask).
Gently rock the flask back and forth to ensure that the entire monolayer is covered
with the Trypsin-EDTA solution. Allow trypsinization to continue until the majority of
the cells (approximately 80%) are rounded up. At this point, gently tap the side of
the flask to release the majority of cells from the culture flask surface.
Important: Avoid leaving cells exposed to the trypsin longer than necessary (no more
than two minutes if using Cyagen’s trypsin-EDTA solution). Care should also be taken
that the cells are not forced to detach prematurely as this may result in clumping.
7. After the cells are visibly detached, immediately add the pre-warmed OriCellTM MSC

Chondrogenic Differentiation
Materials Required
OriCellTM Mesenchymal Stem Cell Chondrogenic Differentiation Medium
(Cat. No. GUXMX-90041)
Chondrogenesis Protocol
1. Calculate the total number of MSC pellet cultures required for your experiment
(2.5×105 MSCs/RFP are needed to form each chondrogenic pellet). Transfer this
amount of cells into an appropriate culture tube.
2. Wash the MSCs/RFP with Incomplete Chondrogenic Medium. Centrifuge the cells at
150 x g for 5 minutes at room temperature and then aspirate off the supernatant.
IMPI0074A2 RASMX‐01201 Page 10 of 15 Resuspend the cells in 1 mL of Incomplete Chondrogenic Medium per 7.5×105 cells.
Centrifuge again at 150 x g for 5 minutes and then aspirate off the medium.
3. Resuspend the MSCs/RFP in Complete Chondrogenic medium to a concentration of
5.0×105 cells/mL.
4. Aliquot 0.5 mL (2.5×105 cells) of the cell suspension into 15 mL polypropylene
culture tubes. Centrifuge the cells at 150 x g for 5 minutes at room temperature.
DO NOT aspirate the supernatant or resuspend the pellet.
5. Loosen the caps of the tubes one half turn in order to allow gas exchange, and
incubate the tubes at 37°C in a humidified atmosphere of 5% CO2. Do not disturb
the pellets for 24 hours.
6. Feed the cell pellets every 2-3 days by completely replacing the medium in each
tube (to avoid aspirating the pellets when aspirating the medium, attach a sterile 1200μL pipette tip to the end of the aspirating pipette). Add 0.5 mL of freshly
prepared Complete Chondrogenic Medium to each tube.
7. After replacing the medium, flick the bottom of the tube to ensure that the pellet is
free floating. Loosen the caps and return the tubes to the 37°C incubator.
8. Chondrogenic pellets should be harvested after 14-28 days in culture. Pellets may
be formalin-fixed and paraffin-embedded for alcian blue stain analysis.
Alcian Blue Staining Procedure
1. The tissue sample should be formalin-fixed and paraffin-embedded already.
2. Staining procedure:
a) Deparaffinize slides and hydrate to distilled water.
b) Stain in alcian blue solution for 30 minutes.
c) Wash in running tap water for 2 minutes.
d) Rinse in distilled water.
e) Visualize under a light microscope and capture images for analysis. Blue
staining indicates synthesis of proteoglycans by chondrocytes.

Troubleshooting
The table below lists some potential problems and solutions for culturing MSCs/RFP.
Problem
Low cell recovery
rate
Cause
Solution
The storage condition does not meet the requirements Purchase a replacement and store in liquid nitrogen for long‐term preservation. Thawing of the cells takes too long Thaw cells for no more than 3 minutes. Cells are incompletely recovered after thawing After aspirating off medium, wash the tube with culture medium twice and transfer all of the cells to the dish. Cells are handled roughly Care should be taken to avoid introducing bubbles during pipetting. Also avoid vortexing and high‐speed centrifugation Medium is not pre‐warmed Warm medium to 37°C before recovery. Mycoplasma contamination Discard the cells in question and disinfect the laboratory environment before recovering the next batch of cells. Slow cell growth
Over digestion Wash the cells with PBS 2‐3 times to remove serum prior to trypsinization (serum will inhibit the function of trypsin). Control the digestion time.
Cell aging
Plating density is too low Increase the plating density. Inappropriate serum and medium Use Cyagen tailor‐made culture media. If
other serum and media products are used, please perform validation to ensure compatibility. Dead cells are not removed promptly Change the medium next day after recovery to ensure removal of all dead cells. Cell Contamination
Discard the cells in question and disinfect the laboratory environment before recovering the next batch of cells. Plating density is too low Some stem cells can secrete factors to support cell growth. Therefore, a certain degree of plating density must be maintained; otherwise, it will lead to cell proliferation slow down and cell aging. IMPI0074A2 RASMX‐01201 Page 13 of 15 Over digestion Cell aging
Wash the cells with PBS 2‐3 times to remove serum prior to trypsinization (serum will inhibit the function of trypsin).
Cells show
spontaneous
differentiation
Ineffective
induction of cell
differentiation
Control the digestion time. The passaging time is not appropriate The cells should be subcultured when reaching 80‐90% confluency in order to avoid contact inhibition. DMSO is not completely removed during cell recovery
Wash the cells with pre‐warmed medium 2‐3 times during recovery.
Differentiation reagents need to be optimized Cell passage is too high
Use Cyagen tailor‐made differentiation media. Use cells at a low original passage number.
