Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Q: 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.

A: yes

Q: Question: Does monoclonal antibody against transforming growth factor Beta 1 influence liver regeneration after resection in large animal experiments?
Answer: We established a large animal model of toxic liver injury that is comparable with CASH. The toxic injury that was induced without pause between administrations was probably more extensive than occurs in CASH, and there was no effect of MAB-TGFβ administration on liver regeneration. MAB-TGFβ administration did not lead to any observable side-effects, indicating that it could be a promising solution for use as an oncologic-targeted treatment.

A:
no
