Example sentences for: osteoblasts

How can you use “osteoblasts” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Alternatively, intracellular bacteria may be the only S. aureus cells capable of inducing TRAIL expression by osteoblasts.

  • We have previously demonstrated that S. aureus induces TRAIL expression in normal human and mouse osteoblasts [ 41 ] . Messenger RNA encoding TRAIL is rapidly and dramatically up-regulated following exposure of osteoblasts to S. aureus . TRAIL mRNA expression is absent in uninfected cultures and shows a dose-dependent response to S. aureus . In contrast to the inducible nature of TRAIL mRNA, the messages encoding death-domain-containing TRAIL receptors are constitutively expressed in human and mouse osteoblasts [ 41 ] . Additionally, TRAIL protein is expressed and secreted following infection of osteoblasts with S. aureus . In contrast, uninfected osteoblasts do not express significant amounts of TRAIL protein.

  • S. aureus at a MOI of 25:1, 75:1, or 250:1 was unable to induce TRAIL expression when direct contact between bacteria and osteoblasts was precluded.

  • Therefore, the ability of TRAIL expressed by S. aureus -infected osteoblasts to mediate osteoblast apoptosis was examined.

  • Direct physical contact between S. aureus and osteoblasts at a MOI of 250:1 induced osteoblast TRAIL protein expression (Fig.
