Figure 1From: The influence of serum, glucose and oxygen on intervertebral disc cell growth in vitro: implications for degenerative disc diseaseThe growth of intervertebral disc cells in monolayer culture. (a) Compared with control cultures, cell numbers at day 7 were significantly decreased in serum-deprived cultures and increased in glucose-deprived cultures. Oxygen deprivation had no significant effect. (b) The proportions of Ki-67-immunopositive cells were also significantly decreased in serum-deprived cultures and increased in glucose-deprived cultures. Oxygen deprivation had no significant effect. Data are presented as mean ± standard error of the mean. *P < 0.05.Back to article page
