| Description |
Interstitial lung disease (ILD) is a group of heterogeneous diseases, including idiopathic pulmonary fibrosis(IPF), hypersensitivity pneumonia, sarcoidosis, and connective tissue-associated interstitial lung disease (CTD-ILD), which is characterized by alveolar unit inflammation and/or fibrinization, leading to the destruction of lung structure and loss of function. In the absence of effective treatment, most ILD may develop diffuse pulmonary fibrosis, leading to structural destruction of lung tissue, diffusion dysfunction, and progressive respiratory failure and death. ILD causes a heavy disease and socio-economic burden, and has become a major public health problem. The target of treatment for interstitial lung disease depends on the type of disease and its clinical manifestations. At present, the existing drugs and treatments such as Pirfenidone and Nintedanib can only alleviate the symptoms of IPF or delay the progression of the disease, and the survival improvement is not obvious, and there is no treatment on the market can cure IPF, Patients with connective tissue have a high burden of lung complications, are prone to ILD complications, and the diagnosis and treatment of ILD are difficult for different CTDs. The evidence to guide the optimization of treatment is limited. Therefore, novel drugs with great therapeutic potential are urgently needed for ILD patients. |

| Description |
A connective tissue cell that normally gives rise to other cells that are organized as three-dimensional masses. In humans, this cell type is CD73-positive, CD90-positive, CD105-positive, CD45-negative, CD34-negative, and MHCII-negative. They may further differentiate into osteoblasts, adipocytes, myocytes, neurons, or chondroblasts in vitro. Originally described as residing in the bone marrow, this cell type is now known to reside in many, if not all, adult organs.; Mesenchymal stem cells (MSCs) are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts, chondrocytes, myocytes, and adipocytes. These cells originate mainly from the mesoderm of the embryo, which forms connective tissues, muscle, and the circulatory and urinary systems. However, in adults, MSCs are found in multiple tissues, including bone marrow, adipose tissue, the umbilical cord, and dental tissues.
The primary function of MSCs is to maintain and repair the tissues in which they are found. When damage occurs, the MSCs are able to migrate to the site of injury, where they aid in regenerating the damaged tissue by differentiating into the required cell type and by secreting growth factors that enhance tissue repair and reduce inflammation. Furthermore, MSCs can also act as immunomodulators, suppressing immune reactions and reducing inflammation, both locally and systemically.
Apart from their role in tissue maintenance and repair, MSCs are integral to the field of regenerative medicine and are being investigated for their therapeutic potential in various clinical settings. Owing to their multipotent nature, immunomodulatory activity, and the relative ease of isolation, these cells can be engineered and translated into therapies to treat a variety of diseases, including bone and cartilage defects, liver diseases, heart disorders, and autoimmune diseases, amongst others. They have also been used as vectors for anticancer agents and in cell and gene therapy applications.
(This extended description was generated by ChatGPT and reviewed by the CellGuide team, who added references, and by the CL editors, who approved it for inclusion in CL. It may contain information that applies only to some subtypes and species, and so should not be considered definitional.); Many but not all mesenchymal cells derive from the mesoderm. MSCs are reportedly CD3-negative, CD4-negative, CD5-negative, CD8-negative, CD11a-negative, CD11b-negative, CD14-negative, CD19-negative, CD29-positive, CD31-negative, CD34-negative, CD38-negative, CD40-negative, CD44-positive, CD45-negative, CD49-positive, CD54-positive, CD66b-negative, CD79a-negative, CD80-negative, CD102-positive, CD106-positive, CD117-positive, CD121a-positive, CD121b-positive, CD123-positive, CD124-positive, CD133-negative, CD146-positive, CD166-positive, CD271-positive, B220-negative, Gr1-negative, MHCI-positive, MHCII-negative, SSEA4-negative, sca1-positive, Ter119-negative, and glycophorin A-negative. Cultured MSCs are capable of producing stem cell factor, IL7, IL8, IL11, TGF-beta, cofilin, galectin-1, laminin-receptor 1, cyclophilin A, and MMP-2. |
