Opis:
Poly(L-lactide-co-glycolide) (PLGA) scaffolds of pore size within the range of 250–320 μm were produced by solvent casting/ porogen leaching method. Afterwards, they were modified through adsorption of collagen type I and incubation in simulated body fluid (SBF) to allow deposition of hydroxyapatite (HAp). The wettability of the scaffolds was measured by sessile drop test. Scanning electron microscopy (SEM) evaluation and energy dispersive X-ray analysis (EDX) were also performed. SEM evaluation and EDX analysis depicted the presence of HAp deposits and a collagen layer on the pore walls on the surface and in the bulk of the scaffolds. Wettability and water droplets penetration time within the scaffolds decreased considerably after applying modifications. Human mesenchymal stem cells (hMSC) were cultured on the scaffolds for 28 days and cell morphology, proliferation and differentiation as well as calcium deposition were evaluated. Lactate dehydrogenase (LDH) activity results revealed that cells cultured on tissue culture polystyrene (TCPS) exhibited high proliferation capacity. Cell growth on the scaffolds was slower in comparison to TCPS and did not depend on modification applied. On the other hand, osteogenic differentiation of hMSC as confirmed by alkaline phosphatase (ALP) activity and mineralization results was enhanced on the scaffolds modified with hydroxyapatite and collagen.

Opis:
Cellular therapy, as a part of regenerative medicine, implies to the treatment of human disorders with cells as a medical product, so called – “living drugs”. Usually such therapy is applied when other alternative efficient pharmacological therapies are not available. Stem cells of different origin: 1) tissue specific e.g. hematopethic, epithelial, neuronal, limbal; 2) mesenchymal stem cells (MSC) harvested from variety of tissues; 3) pluripotent stem cells: embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC) – serve as a source of cells for regenerative medicine application, depending upon disease and application re- quirements. Currently MSC are the type of stem cells that are most frequently used in registered regenerative medicine clinical trials. In this paper we provide the information on the application of cell therapy in orthopedics, hematology, ophthalmology, dermatology, gastrology and neurology. The influence of origin of MSCs and iPSCs on their mode of action as therapeutic, regenerative agents are discussed. Advantages and disadvantages of application of different cell types for cell therapy are underlined. Last, but not least current low regulations in Poland and requirements of European regulatory bodies for cell therapy are pointed out and discussed.
