First of all I'm new here and want to thank you for your generous giving of knowledge and advice. I have already spent a few hours poking around.
I am a newish to fruit trees. I live in the Seattle area and have bought several apple (Chehalis, Karmjin, Sweet 16, Honeycrisp), cherry (Angela, D Stella, Rainier), pear (Conference, Aurora) and plum (Stanley) trees over the last couple years. I live on a steep slope so it has been somewhat of a challenge prepping each ivy and blackberry covered site for planting. I just plugged in an Angela cherry. When I pruned it, I noticed a tan-colored core inside the stem. I recall reading one time that this might indicate disease. I saw it in the three stems I pruned. I had the tree heeled in over the winter.
Can someone guess the cause of this and recommend as to whether I should remove and dispose of the tree if it is disease, as to not infect nearby trees. I garden organically only.
Thanks!

…anyone know how freeze damage manifests in cherry trees? Though we’ve had a basically mild winter, those early weeks of near record-setting cold were brutal! …did you get in on any of that up north 
Folks, if the cambial cells (under the bark) are vivid green, has there been damage..? It seems strange it would present itself at the core, only. – is there green under the bark (scrape a pruned piece)?
Ted Swensen has an excellent article in the current HOS, Pome News: Bacterial Canker – Gumosis of Stone Fruit. …but that deals with ‘cankers’ on infected cherry trees, with eventual oozing from their bark, no mention of discolored interiors…
My inclination would be to leave it, see if it leafs out on ‘schedule,’ if not, it should be quite easy to replace 
Thanks for your response. Yes we had some record cold (and dry) temps earlier and I may have not had it sufficiently protected from the cold. I bought it bare root and haven't seen it in active growth yet.
I am hoping you're right and it is from the winter and not something like Verticillum Wilt which sounds possible too.
Here's to an early Spring!
