delete or keep special rows in a cell array based on specific column values

I have a cell array with 2 columns. first column is array of strings, and second is numeric values. I would like to delete the rows in which the first column does not contain \w & \s at all using reqexprep. example of cell array:

'summits,'  '-1'
'.'          ' 3'
'greenhouse'  ' 0'
'hello world'  '-2'
'abandoned'  '-2'

But, I have 2 problems:

1. Item two how to delete the whole row which satisfies the condition, like the second row in example which contains '.' in the first column,
2. how to keep a row which just have additional "," in the first column, like the first row in example(I mean that I want to delete ',' and keep 'summits' and its row)! It's a bit complicated!!

I would appreciate any help,

Thank you in advance

A={'summits,'  '-1'
'.'          ' 3'
'greenhouse'  ' 0'
'hello world'  '-2'
'abandoned'  '-2'}
d=cellfun(@(x) regexprep(x,'[,\.]',''),A(:,1),'un',0)
idx=cellfun(@isempty,d)
A(:,1)=d
A(idx,:)=[]
