question:
Question: Are ovarian stem cells always accompanied by very small embryonic-like stem cells in adult mammalian ovary?
Answer: VSELs have remained poorly studied till now because of their very small size and rare occurrence. Spinning cells obtained after enzymatic digestion of ovarian tissue at a speed of 1000G (rather than 1200 rpm) throughout processing allows reliable detection of the VSELs by flow cytometry. VSELs exist in aged, chemoablated and non-functional ovary and providing a healthy niche to support their function offers an interesting strategy to manage infertility.
answer:
yes


question:
Question: Are levels of soluble CD30 in cord blood and peripheral blood during childhood correlated with the development of atopic disease or a family history of atopy?
Answer: These findings indicate that the sCD30 concentration in cord blood is not a reliable prognostic indicator of, nor a useful diagnostic marker for, atopic disease in children up to 7 years of age. If such correlations do exist, they might be masked by age-dependent variations in the circulating levels of sCD30, which may reflect individual differences in the maturation of children's immunological responses.
answer:
no


question:
Question: Is serum interleukin-22 ( IL-22 ) increased in the early stage of Hashimoto 's thyroiditis compared to non-autoimmune thyroid disease and healthy controls?
Answer: Serum IL-22 is increased in newly diagnosed, untreated HT patients, as compared to thyroid autoimmune disease-free individuals. Our data suggest that IL-22 could play some role in the development of HT.
answer:

yes
