'query order to appear for examination' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'for examination' is the wordplay.
'for' becomes 'stemcell' (I can't explain this - if you can you should believe this answer much more).
'examination' becomes 'research' (I've seen this before).
'stemcell'+'research'='STEM CELL RESEARCH'

Can you help me to learn more?

(Another definition for stem cell research that I've seen is " that hopes to find new remedies".)

I've seen this clue in The Times.
