Can anybody tell me from where is this tissue taken and in with techique is it colored please ?
I might as well be wrong, not being an histologist, but that's probably a classic: mammal liver tissue, (poorly) H&E stained, also showing Kupfer cells having phagocytosed something black (carbon particles from indian ink?).
It looks like a classic HE stain. (https://en.wikipedia.org/wiki/H%26E_stain)
Unfortunately I cannot help with identifying the source of the tissue as you have not specified a organism of origin.
