Hypothesis

Can P-glycoprotein expression be found in normal and reactive bone marrows?

Conclusion

P-glycoprotein expression was found in a significant proportion of normal and reactive bone marrow samples.

Supporting Evidence

  • 27 of 53 samples were positive for P-glycoprotein expression.
  • 5 of 23 normal samples and 13 of 28 reactive samples were positive for P-glycoprotein.
  • The percentage of positive cells ranged from 2% to 80%.

Takeaway

The study looked at how a protein called P-glycoprotein is found in bone marrow, and it turns out that many samples had this protein, even in healthy people.

Methodology

Immunocytochemistry and PCR were used to detect P-glycoprotein expression in bone marrow samples.

Limitations

The study had a small sample size and did not explore lineage specificity of P-gp expression.

Participant Demographics

26 men and 27 women, ages ranged from 15 to 87 with a mean age of 48 years.
