Abstract
Description
[Technical field] 【0001】 The present invention relates to an agent for promoting muscle satellite cell proliferation, a product for promoting muscle satellite cell proliferation, an agent for inhibiting muscle satellite cell proliferation, and a product for inhibiting muscle satellite cell proliferation. [Background technology] 【0002】 In the bodies of mammals, including humans, myoblasts differentiate into myotubes, which fuse to become muscle fibers, and connective tissue fills the spaces between the cells to form muscle bundles, which then gather together to form muscles. Muscles play an important role in energy metabolism, the intake of sugar and other substances into the body, daily movements such as walking and maintaining posture, and physical activities such as exercise, but they are known to decrease with age. 【0003】 Muscle satellite cells exist between the cell membrane and the basement membrane of muscle fibers. When activated, muscle satellite cells differentiate into myoblasts and then into muscle cells. Multiple muscle cells fuse together to form myotubes, which then form muscle fibers. 【0004】 Although a satellite cell differentiation promoter containing hawthorn or rosea has been proposed to improve muscle mass and strength (Patent Document 1), the proliferation of satellite cells has not been fully studied. To prevent the decline in quality of life associated with aging and live longer and healthier lives, external and oral products that promote and inhibit the proliferation of satellite cells are desired.

The cryotube in which muscle satellite cells (HSkMC, manufactured by LIFELINE) had been frozen and stored was removed from the liquid nitrogen tank for cell storage and immersed in a thermostatic bath to thaw the suspension. 2. The suspension was transferred to a 50 mL centrifuge tube, and the inside of the ceramic tube was washed with culture medium. 3. Culture medium (StemLife Sk Comp kit, manufactured by LIFELINE) was added to the suspension to make the total volume 30 mL. 4. Of the total volume of 30 mL, 15 mL was seeded into two T75 flasks. 5. The T75 flask was placed in a CO2 incubator (37.0°C, 5.0% carbon dioxide). 6. After 1 day, the medium was changed, and then every other day. 7. Remove the T75 flask from the CO2 incubator and observe under a phase contrast microscope to confirm that the satellite cells were in a subconfluent state. 8. Satellite cells were detached from the T75 flask by trypsinization and collected in a 50 mL centrifuge tube. The number of viable satellite cells was counted by trypan blue staining. 【0036】 A muscle satellite cell proliferation test was performed as follows. 1. Muscle satellite cells were seeded into a 96-well plate at 2000 cells / 100uL / well and cultured for 24 hours (37.0℃, 5.0% carbon dioxide). 2. The medium was removed by suction, and each plant extract was added at 200 uL / well. The cells were then cultured for 3 days (37.0°C, 5.0% carbon dioxide) in a medium not containing growth factors. 3. After incubation, the medium was removed and the cells were fixed with 100 uL of methanol at 25° C. for 20 minutes. 4. The plate was inverted on a paper towel to remove the methanol, and then washed twice with PBS. 5. After removing the PBS, a blocking solution was added and shaken at room temperature (450 rpm). 6. The blocking solution was removed, and 30 ul of primary antibody (Rb pAb to PAX7 (abcam ab187339) was added and incubated overnight at 4°C. 7. The reaction liquid was discarded and the plate was washed once with PBS. 8.50 ul of secondary antibody (Alexa Fluor 633 goat anti-rabbit IgG (H+L) (Invitrogen A21070)) 1 / 1000 and hoechst33342 1 / 1000 in blocking solution were added, and the plate was placed on a shaker (450 rpm) at room temperature under dark conditions for 1 hour. 9. The liquid was discarded, and the cells were washed once with PBS, after which the cell count was measured using ImageXpress Micro (Molecular Devices). 10. The ratio of the cell number in each test solution to the cell number in the control without added plant extract was calculated as the muscle satellite cell proliferation rate. 【0037】 The results are shown in Table 1. The test solutions containing soybean seed extract and oolong tea leaf extract promoted the proliferation of muscle satellite cells. The test solutions containing soybean seed extract and oolong tea leaf extract further promoted the proliferation of muscle satellite cells. 【0038】 [Table 1] 【0039】 The results are shown in Table 2.
