The current invention reports the use of meta-tyrosine for increasing the specific productivity of a eukaryotic cell that produces/expresses a polypeptide. In the current method it is not necessary to perform a temperature-, osmolality- or pH shift or to add drugs like valproic acid or sodium butyrate to modulate the specific productivity of the cultivated cells. The method does not affect cell viability or product titer.

The present invention is primarily directed to provide a new composition for a medium which can be used for differentiation induction from somatic cells to brown adipocytes.

The present invention can include, for example, a composition for a medium used in differentiation induction from somatic cells to brown adipocytes, wherein the composition comprises the following seven components: a thyroid hormone receptor agonist, a glucocorticoid receptor agonist, a phosphodiesterase inhibitor, insulin, an ascorbic acid derivative, albumin, and an antibiotic.

According to the present invention, direct differentiation induction from somatic cells to brown adipocytes can be effectively performed. In addition, according to the present invention, it is possible to effectively maintain brown adipocytes.

The present disclosure relates generally to therapeutic agents that may be useful as modulators of Integrated Stress Response (ISR) pathway.

The present specification provides a method of producing induced functional astrocytes (iAs) from human pluripotent stem cells substantially more rapidly than previously achieved. These iAs express biomarkers and have functional characteristics typical of natural astrocytes. The iAs are useful in the exploration of astrocyte biology, pathophysiology, and in models of neurologic diseases and disorders.

A method of making an erythroid cell comprising elevated levels of a target protein or polypeptide, the method comprising: a) provision of an erythroid progenitor which is able to express the target protein or polypeptide; b) expression of the target protein or polypeptide; and c) maturation of the erythroid progenitor into the erythroid cell; wherein during maturation of the erythroid progenitor into the erythroid cell, the target protein or polypeptide is configured and/or inhibited such that ubiquitination of the target protein or polypeptide is hindered or prevented. Erythroid cells, pharmaceutical compositions and methods of use related thereto, and a method of screening for proteins or polypeptides degraded by ubiquitination during maturation of an erythroid progenitor are also provided.
