Extract Text Between 2 Points Of Reference

I need to extract text from a cell between 2 predetermined characters. Below find all possible cases and what result (after extraction) should look like:

data cell Extracted
o9.5-105 9.5
o9-105 9
o10.5-105 10.5
o10-105 10
o9.5+105 9.5
o9+105 9
o10.5+105 10.5
o10+105 10
u9.5-105 9.5
u9-105 9
u10.5-105 10.5
u10-105 10
u9.5+105 9.5
u9+105 9
u10.5+105 10.5
u10+105 10

Basically I need to extract numbers between (to the left) o or u and to the right + or -. The string ends always with 3 numbers if it. I have also attached excel file of these two rows for your convenience.
