INTRODUCTION In the past decade human adipose tissue has been identified as a source of multipotent stem cells. Adipose tissue derived stem cells (ASCs) are characterised by immunosuppressive properties and low immunogenicity. Therefore, they can be used in regenerative medicine, as well as applied to induce graft tolerance or prevent autoimmunity. ASCs can(More)
Internally quenched cathepsin L (Cat L) substrate ABZ-Bip-Arg-Ala-Gln-Tyr(3-NO2)-NH2 with high specificity constant (kcat/KM=2.6×10(7)M(-1)s(-1)) was synthesized. The resultant compound displayed high selectivity over other members of the cathepsin family (B, S, X, V, C, K, H, F, D, and A). Activity of Cat L at picomolar (pM) concentrations was found using(More)
The aim of the present study was to examine the effect of 1,25(OH)2D3 (calcitriol) on SMC (smooth muscle cell) migration, especially in the context to atherogenesis. SMCs were obtained from the aortas of newborn Wistar rats by enzymatic digestion. Different aspects of cell behavior during migration in culture were examined by phase contrast, fluorescence(More)
Podocyte injury is associated with progression of many renal diseases, including diabetic nephropathy. In this study we examined whether aldose reductase (AR), the enzyme implicated in diabetic complications in different tissues, is modulated by high glucose and osmolarity in podocyte cells. AR mRNA, protein expression, and activity were measured in mouse(More)
The epidermis is a self-renewing tissue which regenerates constantly. It consists mainly of keratinocytes of various degree of differentiation, from the proliferative basal layer to the terminally differentiated horny layer. Keratinocytes are specialized cells responsible for cohesion, barrier functions, and immunological reactions. The maintenance of(More)
OBJECTIVES The aim of this study was to investigate plasma concentrations of four pro-inflammatory cytokines (IL17a, IL6, TNFα and IL12p70) in patients with myocardial infarction and to analyse them according to presence of depression observed during first 6 months after myocardial infarction. METHODS In 44 patients with the first acute STEMI (ST segment(More)
A series of linear and cyclic fragments and analogs of two peptides (OGTI and HV-BBI) isolated from skin secretions of frogs were synthesized by the solid-phase method. Their inhibitory activity against several serine proteinases: bovine β-trypsin, bovine α-chymotypsin, human leukocyte elastase and cathepsin G from human neutrophils, was investigated(More)
ESC (epidermal stem cells) play a central role in the regeneration of human epidermis. These cells are also responsible for wound healing and neoplasm formation. Efficient isolation of ESC allows their use in medicine and pharmacy as well as in basic science. Cultured keratinocytes and ESC may be used as biological dressing in burn injuries, chronic wounds(More)
Wound healing is a complex process which depends on the presence of various types of cells, growth factors, cytokines and the elements of extracellular matrix. A wound is a portal of entry for numerous pathogens, therefore during the evolution wound healing process has formed very early, being critical for the survival of every individual. Stem cells, which(More)
INTRODUCTION Skin malignancies are the most prevalent neoplasms seen in organ transplant recipients (OTRs). Immunosuppressive treatment has been attributed to play a causative role in malignancy development. The aim of the study was to assess cytokine concentrations involved in cytotoxic and regulatory responses in patients after organ transplantation (Tx).(More)
