The currently studied samples 13 and 14 are morphologically similar to the previously studied samples 3 and 4 - i.e. their particles are mostly oblong in shape and show no signs of lamellar structure.
Should I use the definite articles here, or should they be dropped, because we don't use an article before a numbered noun ("Which way is room 213?")

I'm trying to apply the article to my "room" example:
Which way is the (?) currently renovated room 213?
