Tissue vascularization is requisite to successful cell‐based therapies, biomaterial design and implant integration. Thus, known problems in ossointegration of avascular implants in connection with the generation of bone tissue reflect arrays of general problems of socio‐economic relevance existing in reparative medicine still waiting for to be solved. For this purpose, morphogenesis and remodeling of endothelial angio‐architectures in tissue and in vitro by isolated non‐mitogenic angio‐morphogens [angiotropins] are considered in terms of their structure, function and action mechanisms. Extracellular angiotropins are secreted by activated leukocytes/monocytes/macrophages. They are a family of cytokines with morphogen bioactivity selectively directed to endothelial cells. Their structure was deciphered as metalloregulated copper‐ribonucleoproteins [CuRNP ribokines]. They are built up of angiotropin‐related S100‐EF‐hand protein [ARP] and highly modified and edited 5'end‐phosphorylated RNA [ARNA], complexed together by copper ions. Oxidant‐sensitive ARNA and their precursors represent novel types in a RNA world: They are the first isolated and sequenced forms of extracellular RNA [eRNA], may act as cytokine and bioaptamer, contain isoguanosine [crotonoside] as modified nucleoside and show up copper as RNA‐structuring transition metal ion. By metalloregulated bioaptamer functions, ARNA impart novel biofunctions to RAGE‐binding S100‐EF‐hand proteins. Angiotropin morphogens were shown suitable for neointiation and remodeling of blood vessel patterns in different, adult, embryonal and artificial tissues. These neovascular patterns manifest regulated hemodynamics for preventing tissue necrosis, supporting tissue functions and promoting wound healing. As evaluated in skin and muscle vascularization, the neovascular patterns are integrated into homeostatic control mechanisms of tissue. Thus, the morphogens show up beneficial perspectives and are suggested useful tools for further investigations in angiotherapy, engineering of blood vessel patterns in tissues and biocompatible artificial organs as well as in the preparation of novel implants with morphogen‐coated surfaces.
