Podobnos\u0165 s filmovou postavou Predstavi\u0165 si t\u00fato schopnos\u0165 je zlo\u017eit\u00e9, je to nie\u010do podobn\u00e9, ako hlavn\u00fd hrdina filmu Podivn\u00fd pr\u00edpad Benjamina Buttona, ktor\u00fd sa narodil ako starec a postupne mladol a\u017e do stavu bato\u013ea\u0165a. Tak isto to rob\u00ed aj med\u00faza. Podstata je v tom, \u017ee ak sa vyvinie do star\u0161ieho \u0161t\u00e1dia pr\u00edpadne nestane u nej kr\u00edzov\u00e1 situ\u00e1cia, to znamen\u00e1 \u017ee bu\u010f ochorie alebo hladuje, sama na\u0161tartuje proces sebaomladzovania a to jej zabezpe\u010d\u00ed pre\u017eitie. Vysvetlenie je jednoduch\u00e9, z med\u00fazov\u00e9ho \u0161t\u00e1dia sa vracia sp\u00e4\u0165 do polypov\u00e9ho, a to prebehne vtedy, ak sa membr\u00e1na klob\u00faka z\u00e1rove\u0148 s ch\u00e1padlami za\u010dne scvrk\u00e1va\u0165 a op\u00e4\u0165 sa z nich stane polyp, \u010do je vlastne \u0161trukt\u00fara podobaj\u00faca sa rastlin\u00e1m. Uchyt\u00e1va sa pod vodnou hladinu a\u017e na dne. Pritom si \u010diasto\u010dne pom\u00e1ha transdiferenci\u00e1ciou buniek, \u010do je proces, ke\u010f sa bunky pretransformuj\u00fa na in\u00fd typ bez preru\u0161enia bunkov\u00fdm delen\u00edm. T\u00fdmto \u0161t\u00fdlom je schopn\u00e1 donekone\u010dna meni\u0165 stavbu svojho tela. Neuverite\u013en\u00e9 regenera\u010dn\u00e9 schopnosti Pre \u010dloveka je predstava toho, \u017ee by sme to dok\u00e1zali tie\u017e, ve\u013emi l\u00e1kav\u00e1, ale zatia\u013e neuskuto\u010dnite\u013en\u00e1. Je v\u0161ak pravda, \u017ee transdiferencia\u010dn\u00fd proces do istej miery vyu\u017e\u00edva aj \u010dlovek. Pr\u00edkladom je situ\u00e1cia, ak sa v\u00e1m po sp\u00e1len\u00ed poko\u017eky na slnku sama po nieko\u013ek\u00fdch d\u0148och zahoj\u00ed alebo modrina sa tie\u017e o nejak\u00fd \u010das sama rozplynie… To dok\u00e1\u017ee aj na\u0161e telo, ale od nesmrte\u013enosti je to ve\u013emi vzdialen\u00e9.
