Is there a difference between CD34 and CD34+?

Eileen and all,

The "+" in CD34+ simply refers to being positive for the CD34 cell surface marker. The
absence of  the "+" in CD34 lymphocytes is just shorthand (or laziness).

  I am a data manager for a pharmaceutical company and have the simple
  question what is the meaning of the + in CD34+? and is CD34 lymphocytes the
  same as CD34+ lymphocytes?

  Many thanks,
