nuclei

I'm a little stuck... Click here to teach me more about this clue!

'middle parts' is the definition.
'nuclei' can be an answer for 'parts' (nucleus is a kind of part). I am not certain of the 'middle' bit.

'in clue edited' is the wordplay.
'edited' indicates an anagram.
'in'+'clue'='inclue'
'inclue' is an anagram of 'NUCLEI'.

Can you help me to learn more?

(Other definitions for nuclei that I've seen before include "Centres of atoms" , "More than one central part" , "Central cores" , "Kernels" , "Cores of atoms" .)

I've seen this clue in The Times.
