In the present peptides are described which include between Four and six amino acid residues and with biological activity, which are short Fragments of the Peptide HB 107 (mpkekvflkiekmgrnirn), which is a fragment of the antimicrobial Protein cecropin B and presented. Age related to the stimulation of proliferation and Migration of the cells.The peptides of this include between Four and six contiguous amino acid residues, which are located in positions 11 and 16 hb107 (mpkekvflkiekmgrnirn), i.e., ekmgrn, agents and are useful for the treatment of wounds in the skin For example, it may be due to diabetic ulcers.The peptides are also effective to prevent and reverse the damage on the surface of the skin that has been caused by various Environmental factors.It is noteworthy that the therapeutic effects of the peptides according to the present are manifested in Concentrations equal to or greater than those that would be required should the Peptide HB 107, these peptides represent a cheaper and more versatile. Llar effective Therapies.In This also describes methods that can be produced and used the peptides according to the present.En la presente se describen péptidos que comprenden entre cuatro y seis residuos de aminoácidos y que presentan actividad biológica, que son fragmentos cortos del péptido HB-107 (MPKEKVFLKIEKMGRNIRN), que a su vez es un fragmento de la proteína antimicrobiana cecropina B, y que presentan propiedades relacionadas con la estimulación de la proliferación y la migración de las células. Los péptidos de acuerdo con la presente comprenden entre cuatro y seis residuos de aminoácidos contiguos, que están localizados entre las posiciones 11 y 16 de HB107 (MPKEKVFLKIEKMGRNIRN), es decir, EKMGRN, y son agentes útiles para llevar a cabo el tratamiento médico de las heridas en la piel, que por ejemplo, pueden deberse a úlceras diabéticas. Los péptidos también son eficaces para prevenir y revertir el daño en Ia superficie de Ia piel que ha sido provocado por
