摘要:
Idiopathic pulmonary fibrosis (IPF) is currently the most fatal form of idiopathic interstitial lung disease in which persistent lung injuries result in scar tissue formation. Provided are methods and compositions for the treatment of pulmonary conditions such as fibrosis. Lung spheroid cell-derived conditioned media (LSC-CM) and exosomes (LSC-EXO) are used to treat different models of lung injury. Inhalation treatment with LSC-CM and LSC-EXO-derived compositions can attenuate and/or reverse bleomycin- and silica-induced fibrosis, reestablish normal alveolar structure and decrease extracellular matrix accumulation.

Provided are a clinical-grade autologous bronchial basal cell, a transfusion formulation thereof, and a preparation process. The preparation process comprises the following steps: extracting in vitro active bronchial brush biopsy tissue for digestive treatment, and collecting cells after digestion is terminated; performing plating culture on the digested cells by using a culture plate having trophoblast cells plated thereon, collecting cells, performing amplification culture on the digested cells by using a culture plate having trophoblast cells plated thereon, and when cells grow to cover 50%-90% of the surface area of the culture plate, performing secondary culture; and when secondary culture cells grow to cover 85%-95% of the surface area of a culture dish, digesting and collecting adhered cells, and washing. The prepared bronchial basal cell can be used for repairing damaged lung tissue.
摘要:
The present invention relates to a composition for relieving and treating burns and bedsores comprising the animal lung tissue extract as an active ingredient, wherein the composition of the present invention suggests that the protective effect of animal lung tissue extract and/or propionic acid on skin damage is related to not only inflammation inhibition but also regeneration and angiogenesis of fibrous tissues. It can be used as a therapeutic agent for these diseases by exhibiting industrially available effects related to the treatment of burns and bedsores.
摘要:
The present invention relates to an isolated population of cell suspension from a mammalian fetal pulmonary tissue, wherein said fetal pulmonary tissue is at a developmental stage corresponding to that of a human pulmonary organ/tissue at a gestational stage selected from a range of 20 to 22 weeks of gestation, and a conditioning protocol comprising Naphthalene treatment, for use in treating a disease or condition in which regeneration of epithelial, mesenchymal and/or endothelial tissue is beneficial in a subject in need thereof.
摘要:
Embodiments of the invention relate to human stem cells and their therapeutic use in the treatment and/or prevention of lung diseases. Provided herein are compositions comprising c-kit positive human lung stem cells and methods of preparing and using c-kit positive human lung stem cells for the treatment and/or prevention of lung diseases.
摘要:
This application describes an apparatus and a method for the treatment of a damaged lung, heart, or other organ or tissue using cells contained in the apparatus and a liquid interface that allows communication with the circulation of the damaged organ or tissue. The apparatus can be used to treat the organ inside or outside the body. The apparatus is designed to sit outside the body but a similar apparatus is envisioned that is implantable. The apparatus contains a porous material or matrix that the cells are grown on, and the volume of the apparatus provides that it can contain a therapeutically useful number of cells in the range 0.5×10e6 to 200×10e6.
摘要:
The present invention relates to compositions and methods for generating populations of tissue precursor cells from pluripotent cells, and preferably induction of stem cells into definitive endoderm to generate anterior foregut endoderm from pluripotent cells. The anterior foregut endoderm cells can then be differentiated into an alveolar epithelial type II cell.
摘要:
A hybrid gel comprising a particulate decellularized tissue (obtained by pulverizing animal-derived biological tissues that are decellularized (decellularized biological tissues)), fibrinogen and thrombin; a cell culture material comprising the hybrid gel; a method for preparing the hybrid gel; and a kit comprising a particulate decellularized tissue and a biological tissue adhesive are provided. The hybrid gel of the present invention exerts the effect to promote differentiation and gain of function of stem cells and the therapeutic effect to a variety of diseases.
