摘要:
Methods and compositions for treating and reducing retinal degeneration using progenitor cells and conditioned media from progenitor cells, such as postpartum-derived cells are disclosed. Genetic factors and receptors expressed by the progenitor cells that aid in protection of retinal cells and inhibition of apoptosis of retinal cells such as photoreceptor cells are also disclosed.

본 발명은 SOD3를 과발현하는 줄기세포를 유효성분으로 포함하는 염증성 질환의 예방 또는 치료용 약학적 조성물을 제공한다. 본 발명자는 SOD3를 과발현하는 중간엽 줄기세포 (MSC)가 일반 MSC에 비해 더욱 강한 항산화 활성, 면역조절기능을 가진다는 것을 확인하였으며, 따라서, SOD3를 과발현하는 MSC는 염증성 질환이나 자가면역질환, 장기이식 거부반응 등에 대하여 효과적인 치료제가 될 수 있다.
摘要:
The current disclosure provides methods for reprogramming mammalian somatic cells by regulating the expression of endogenous cellular genes. Cellular reprogramming of somatic cells can be induced by activating the transcription of embryonic stem cell-associated genes (e.g., oct.3/4 ) and suppressing the transcription of somatic cell-specific and/or cell death-associated genes. The endogenous transcription machinery can be modulated using synthetic transcription factors (activators and suppressors), to allow for faster, and more efficient nuclear reprogramming under conditions amenable for clinical and commercial applications. The current disclosure further provides cells obtained from such methods, along with therapeutic methods for using such cells for the treatment of diseases amendable to stem cell therapy, as well as kits for such uses.
摘要:
Provided in some aspects are methods and compositions for preserving platelets or other cells. In some embodiments, a platelet storage media or cell storage media may comprise a low molecular weight polyethylene glycol ( e.g. , PEG-400) to allow for extended storage and/or refrigeration of the platelets or cells.
摘要:
The present invention provides methods for preparing modified blood clots comprising removal of the cellular content of the blood clots. The invention further provides uses of the modified blood clots as therapeutic agents and as delivery vehicles for cells, bio- molecules and other agents.
摘要:
The invention relates generally to the fields of biology and health sciences. More particularly, the invention relates to compositions and methods for modulating cellular physiology and pathological processing using a combination of compounds that can be found in amniotic membrane tissue and umbilical cord tissue preparations.
摘要:
The present invention shows that CB plasma contains soluble NKG2D ligands and that the incubation of PBMCs with CB plasma results in decreased cytotoxicity, decreased proliferation and inhibition of IFNy production by NKG2D bearing cells, in particular, NK cells. Interaction of NKG2D with soluble NKG2D ligand leads to blocking of the NKG2D receptor, and renders NKG2D bearing cells refractory to activation and inhibits cell functions. Notably, this is a mechanism naturally employed by tumor cells or viruses such as CMV to escape the immune system.
