• Doxycycline, an anti-bacterial agent, had dramatic effects on hESC/iPSC survival and promoted self-renewal.
• Doxycycline supplementation can reduce the frequency of media changes and the amount of media required by 1/3.
• Doxycycline effects can be practically utilized to save the cost and labor of hESC/iPSC culturing.
Culturing human embryonic stem and induced pluripotent stem cells (hESCs/iPSCs) is one of the most costly and labor-intensive tissue cultures, as media containing expensive factors/cytokines should be changed every day to maintain and propagate undifferentiated hESCs/iPSCs in vitro. We recently reported that doxycycline, an anti-bacterial agent, had dramatic effects on hESC/iPSC survival and promoted self-renewal. In this study, we extended the effects of doxycycline to a more practical issue to save cost and labor in hESC/iPSC cultures. Regardless of cultured cell conditions, hESCs/iPSCs in doxycycline-supplemented media were viable and proliferating for at least 3 days without media change, while none or few viable cells were detected in the absence of doxycycline in the same conditions. Thus, hESCs/iPSCs supplemented with doxycycline can be cultured for a long period of time with media changes at 3-day intervals without altering their self-renewal and pluripotent properties, indicating that doxycycline supplementation can reduce the frequency of media changes and the amount of media required by 1/3. These findings strongly encourage the use of doxycycline to save cost and labor in culturing hESCs/iPSCs.
