The mesenteric tissue was cut into 1 × 1 mm tissue fragments with sterile surgical scissors and digested in Dulbecco’s modified Eagle’s medium (Invitrogen) containing 1.5 mg·mL−1 type II collagenase (C6885; Sigma‐Aldrich, St Louis, MO, USA) and 60 U·mL−1 type I DNase (D5025; Sigma‐Aldrich). After 2 h of incubation on a table concentrator (60 r.p.m.) at 37 °C, digestion was stopped with ice‐cold Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum (Invitrogen) and filtered through a 70‐μm filter. The cell mixture was then centrifuged at 300 g for 10 min at 4 °C, and the supernatant was removed. Finally, the cell pellet was resuspended in 5 mL of complete medium and seeded.

Primary mBMSCs were from the femoral bone marrow of wild-type C57BL/6J mice at 3 months of age as previously described.41 (link) The isolated cells were maintained in Dulbecco’s modified Eagle’s medium, containing 15% heat-inactivated fetal bovine serum, 100 U·mL−1 of penicillin and 100 µg·mL−1 of streptomycin sulfate for 3 days (all from Invitrogen). The nonadherent hematopoietic cells were then removed by vigorous washing with phosphate-buffered saline (PBS) three times. The growing colonies were collected by trypsinization after 2 weeks for further passaging and differentiation. The in vivo and in vitro animal procedures were approved by the Committee for the Care and Use of Laboratory Animals of the State Key Laboratory of Oral Diseases, West China Hospital of Stomatology, Sichuan University.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
