Visco-supplement compositions derived from a transcellular fluid, such as human amniotic fluid, human aqueous humor fluid, or human vitreous fluid are described. Also described are methods for treating inflammatory conditions of the musculoskeletal system, such as joint inflammation, and methods of lubricating a joint using the described visco-supplement compositions.

Formulations of human amniotic fluid and methods of use thereof for treatment of lung disorders, and/or injuries have been developed. The formulations are suitable for topical delivery to the lung for treatment of lung disorders including chronic obstructive pulmonary disorders (COPD), asthma, emphysema, bronchiectasis, chronic bronchitis, interstitial lung disease, alpha-1 antitrypsin emphysema, as well as for treatment of acute lung injuries. Methods including administering specifically formulated, diluted sterile de-cellularized human amniotic fluids topically to the lungs, preferably as aerosol droplets, are described. In particular, the methods involving administration of the amniotic fluid formulation in the form of aerosol droplets with size between about 1.5 μm to about 5 μm, preferably from about 2.5 μm to about 3.5 μm, inclusive, using apparatus such as high-efficiency vibrating mesh nebulizers, are described. Formulations described can treat, or prevent one or more symptoms of a chronic lung disorder.

Provided herein is a pre-Caesarean method for collecting amniotic fluid from a patient. A needle is inserted into the incision site for the future C-section, which may be under ultrasound guidance, through which the amniotic fluid is drawn under a low level suction and, optionally, gravity to a sterile collection container. The method encompasses filtering and/or irradiating the amniotic fluid to collect biomolecules of interest such as growth factors and/or stem cells. Also provided is the sterile amniotic fluid or filtrates thereof collected by the method described herein.

Provided herein are methods for treating coronavirus diseases. In one embodiment, the method comprises administering to a coronavirus disease patient a therapeutic amount of decidua stromal cells. In one embodiment, the method comprises administering to the subject a therapeutic amount of decidua stromal cells (DSCs). In some embodiments, the coronavirus disease is SARS, MERS or COVID-19. The method of the disclosure can be used to treat a subject who has acute respiratory distress syndrome (ARDS), acute lung injury (ALI), or both.

Disclosed herein is a pharmaceutical composition containing a neprilysin-overexpressing stem cell, a conditioned medium thereof, and an exosome isolated therefrom as an active ingredient for prevention or treatment of cognitive impairment. Having the functions of protecting nerve cells, inhibiting the accumulation of amyloid beta, known as a cause of cognitive impairment-related disease in animal models, increasing an expression level of acetyl choline, and improving cognitive functions in animal models, the neprilysin-overexpressing stem cells, the conditioned medium thereof, or the exosomes isolated therefrom according to the present disclosure can find advantageous applications in treating cognitive impairment.

Formulations and methods for activating signaling molecules outside a native physiological response are provided. The formulations can include an activator component and a signaling component containing both signaling molecules and mesenchymal stem cells. When a formulation containing both an activator component and a signaling component is injected into or applied to a treatment area, the activator component may activate the signaling molecules of the signaling component which in turn signal the mesenchymal stem cells of the signaling component to regrow, repair or otherwise provide a benefit to the treatment area.
