Disclosed herein are methods and compositions for treating or preventing ovarian failure using fibroblasts or cells derived from fibroblasts. In some embodiments, ovarian failure is pathological, the result of an intervention, or the result of aging. In some embodiments, regenerative fibroblast cells are administered locally into the ovary or pen-ovary areas or systemically. In some embodiments, regenerative cells act to suppress fibrosis of the ovaries, inhibit inflammation, stimulate maturation of immature ovarian progenitor cells, or directly differentiate into oocytes. In some embodiments, regenerative fibroblasts produce factors that inhibit apoptosis of oocytes and/or oocyte progenitors.

Provided is a cell population comprising differentiated cells obtainable by inducing differentiation of pluripotent stem cells, wherein the content ratio of undifferentiated pluripotent stem cells is 0.2% or less.

Methods for preparing capsules, such as micro- and/or nanocapsules from all-aqueous emulsions are described herein. The method includes mixing, combining, or contacting a first electrically charged phase containing a first solute with at least an optionally charged second phase containing a second solute. The solutes are incompatible with each other. The electrostatic forces between the two solutions induce the formation of droplets of a dispersed phase in a continuous phase. The droplets are then solidified to form the capsules.

Embodiments of the disclosure include methods and compositions related to prevention of spontaneous miscarriage in an individual. In certain cases, fibroblasts are provided in an effective amount to an individual in need thereof. Alternatively or in addition, lymphocytes are obtained, cultured with fibroblasts, and provided to an individual. Fibroblasts may modulate an immune response in an individual, thereby reducing the risk of spontaneous miscarriage.

Cell based therapy comprises administration to the lung by injection into the blood system of viable, mammalian cells effective for alleviating or inhibiting pulmonary disorders. The cells may express a therapeutic transgene or the cells may be therapeutic in their own right by inducing regenerative effects.
