Abstract:
The present invention relates to an in vitro blood-brain-barrier (BBB) model comprising a porcine triple co-culture comprising porcine astrocytes, porcine primary brain endothelial cells (BEC's) and porcine pericytes. The invention also relates methods of producing such porcine triple co-cultures and uses thereof.
Abstract:
A microfluidic system for determining a response of cells comprises one or more fluid pumps. The one or more fluid pumps move a fluid across cells within a microfluidic device. The microfluidic device includes a microchannel at least partially defined by a surface having cells adhered thereto, a first port at one end of the microchannel, and a second port at an opposing end of the microchannel. The one or more fluid pumps move the fluid across the cells in a first direction toward the second port and then move the fluid across the cells in a second direction toward the first port.
Abstract:
본 발명은 파브리 병(Fabry disease)의 유도-만능 줄기세포(induced pluripotent stem cells; iPSC) 모델, 이의 제조 방법, 및 상기 iPSC 모델을 파브리 병의 발병 연구 및 치료제 스크리닝 방법에 이용하는 용도에 관한 것으로, 구체적으로 파브리 병 환자의 섬유아세포로부터 파브리 병 유래의 유도-만능 줄기세포(induced pluripotent stem cells; iPSC), 배상체(embryoid body, EB) 및 혈관 세포(vascular cell)의 발생 및 분화를 유도하였으며, 상기 파브리 병 유래의 iPSC는 GLA 단백질의 발현 및 활성이 정상 세포에 비하여 현저히 감소하여 글로보트리아오실세라마이드(globotriaosylceramide, Gb3, CD77)가 축적되는 것을 확인하였고, 파브리 병 유래의 iPSC로부터 혈관 세포로 분화를 유도한 결과, 혈관내피 세포 및 혈관 평활근 세포로 분화되어 마커 단백질을 유의적으로 발현하였으며, 상기 혈관내피 세포 및 혈관 평활근 세포에 파브라자임 효소를 처리하였을 때, Gb3의 축적이 유의적으로 감소하므로, 상기 세포 모델은 파브리 병의 기전 분석 연구 및 치료제 스크리닝 방법을 위한 분석 연구에 유용하게 사용될 수 있다.
Abstract:
Control cells include a stable intact cell and, on the surface of the stable intact cell, a plurality of different antigens. Each of the different antigens corresponds to an antigen of interest. The control cells are employed in methods of evaluating the efficacy of a biological procedure performed on a sample. The method comprises conducting the biological procedure in the presence of the control cells. The control cells are examined to determine the efficacy of the biological procedure.
Abstract:
Flow chambers are provided. In some embodiments, the flow chambers include an inner panel having at least one flow channel having an inlet/outlet opening on each end thereof formed therein, wherein the inlet/outlet openings are adapted to releasably receive a septum; one or more ports adapted to releasably receive a plug and for at least liquid communication with the at least one flow channel, and an outer frame that defines an outer portion of the at least one flow channel and that defines a perimeter of the flow chamber. In some embodiments, the flow chamber has overall dimensions of a standard multiwell plate and the at least one flow channel is located in a position that corresponds to a column location of the standard multiwell plate. Also provided are methods for producing the presently disclosed flow chambers and employing the same to assay biological features of cultured cells and/or tissues.
Abstract:
A three dimensional (3-D) model comprising a scaffold and autologous skin cells, the invention also provides methods of predicting immunogenicity and hypersensitivity or allergic or adverse immune reactions to potential therapeutic compounds, biologies, cosmetics and chemical sensitizers using the 3-D model of skin cells. The methods provide an in vitro assay employing autologous blood derived cells in the 3-D skin equivalent model and is of particular utility in the identification and prediction of skin sensitizers and in particular agents that may cause allergic contact dermatitis. The assay of the present invention provides inter alia methods of screening library compounds for sensitizing activity, identifying optimal therapeutics, especially but not exclusively, monoclonal antibodies and kits therefor.
