A composition comprising cell-derived particles presenting heterologous CD24, wherein the cell is a non-cancerous cell and wherein the composition is substantially devoid of intact cells is disclosed. Methods of producing the cell-derived particles and methods of using the cell-derived particles in treatment of cytokine storm syndrome, tissue injury associated with the inflammation and Coronavirus infection are also disclosed.

A sheet structure comprising two joined extracellular matrix (ECM) tissue or sheet layers and a physiological sensor disposed therebetween; the ECM tissue being derived from a mammalian tissue source that includes small intestine submucosa (SIS), urinary bladder submucosa (UBS), stomach submucosa (SS), urinary basement membrane (UBM), liver basement membrane (LBM), amniotic membrane, mesothelial tissue, placental tissue and cardiac tissue.

The use of fecal matter in the treatment of a subject having autoimmune disease, wherein the fecal matter is autologous to the subject, and preferably administered to the small intestine, preferably the duodenum, of the subject. The fecal matter can be one or more constituents of autologous feces, preferably chosen from the group consisting of bacteria, viruses, bacteriophages, fungi, metabolites, microRNAs, proteins, antibodies, and/or antigens.

Methods are disclosed for dissecting a mucosa and a submucosa from a muscularis propria from a region of an organ of a subject, wherein the organ is not the esophagus. In some embodiments, the organ is in the gastrointestinal tract. These methods include injecting submucosally into the organ of the subject a pharmaceutical composition comprising an extracellular matrix (ECM) hydrogel to form a cushion between the submucosa and the underlying muscularis propria at the region of the organ, wherein the ECM hydrogel has the following characteristics: a) a time to 50% gelation of less than 30 minutes at a temperature of about 37° C.; b) a flow viscosity suitable for infusion into the organ; and c) a stiffness of about 10 to about 400 Pascal (Pa).

Low level light (LLL) can be used to restore a subject's gut microbiota to a state of health. The LLL can be applied directly to the subject's abdomen and/or back, or the LLL can be applied to a feces sample obtained from the subject, which is subsequently administered back to the subject. The subject may be suffering from guy dysbiosis resulting from a variety of different types of bodily stress, such as chemotherapy or radiation therapy.

Methods are disclosed for treating an acute respiratory distress syndrome, such as an acute respiratory distress syndrome associated with a viral infection, such as SARS-CoV2 (COVID-19) in a subject in need thereof. These methods include administering to the subject a pharmaceutical preparation comprising isolated matrix bound vesicles (MBV) derived from extracellular matrix.

The kidney regeneration accelerator that contains a component obtained by decellularizing a mammalian organ. The production method for a kidney regeneration accelerator that involves decellularizing a mammalian organ to obtain a component that includes an extracellular matrix, freeze drying and then pulverizing the component to obtain a powder, and performing a sterilization treatment on the powder. A pharmaceutical composition for use in treating kidney disease that contains a component obtained by decellularizing a mammalian organ. A treatment method for kidney disease that involves applying a pharmaceutical composition that contains a component obtained by decellularizing a mammalian organ to a site to be treated of the kidney of a human or animal kidney disease patient.

The present invention, in some embodiments thereof, is directed to a method for isolating a target microorganism from a sample, including contacting a sample with an antibody having specific affinity to the target microorganism, wherein the antibody is produced by immunizing a host organism using a selected target microorganism, wherein the selected target microorganism is selected by contacting the sample with one or more polynucleotide molecules each having specific affinity to one target microorganism, and determining the presence of the target microorganism in the sample.

Methods of treatment are provided herein, including administration of a population cells modified to enforce expression of an E-selectin and/or an L-selectin ligand, the modified cell population having a cell viability of at least 70% after a treatment to enforce such expression.
