The curren. immun.on.ology artificially ign.res the con.ection.with lymphopoiesis, though is on.y its derivative. Hematopoietic stem cells (HSC) provide physiological regen.ration.of biomass of the host, fetus, an. malign.n. tumors, as well, as the cells’ reparation.after sub-lethally in.urin. in.an. tissues an. their ren.wal. HSC, especially of lymphoid lin.age, are the most vuln.rable of those, which are respon.ible for viability of organ.sm. n.tural an. artificial deficits of HSC determin. agin., multi-organ. syn.romes an. death of the host, because their curren. proliferative resource (CPR) is in.ividually limited at birth, an. is spen.in. irreversibly durin. woun.s’ healin., pregn.n.y, tumor growth, an. on. CPR, bein. an.in.egral value of the n.mber of stem cells alon. the len.th of their telomeres, is a “shagreen.skin., for which the tumor competes with n.rmal tissues as a quasi-embryon.c favorite an. win.er, especially in.the fin.l period of a shorten.n. the life. The primary approach to can.er treatmen. must prioritize the preservation.of CPR remn.n.s, rather than.their destruction. in.order to temporarily halt the malign.n. process. The re-targetin. of HSC from tumors in.favor of n.rmal tissues is the immediate objective of competitive therapy, which allows for preservin. the rest of the CPR host’s resources, especially in.patien.s with advan.ed can.er. However, the con.radictory an. in.ign.fican. practically, the dogma of an.itumor cellular immun.ty con.in.es to domin.te an. hin.er progress in.on.ology.
