The present invention relates to methods of modulating (e.g., reducing) the mannose content, particularly high-mannose content of recombinant glycoproteins.

Methods of differentiating a mesenchymal stromal cell (MSC) to a first non-MSC cell fate, the method comprising contacting the MSC with extracellular vesicles (EVs), matrix-bound vesicles (MBVs) or a combination thereof are provided. Methods of producing artificial tissue by culturing MSCs with two sets of vesicles each comprising EVs, MBVs or both that differentiate MSCs to two different non-MSC cell fates, methods of culturing with reduced growth factors and method of differentiating an MSC to a muscle cell fate are also provided.

Methods of farming, domesticating, or cultivating truffle fungi, including isolation and cultivation methods for producing pure truffle fungi, or mini-truffles, typically a Tuber spp. or an Iamai spp. Examples of truffle include Tuber melanosporum, Tuber magnatum, Tuber aestivum, Tuber uncinatum, Tuber borchii, Imaia spp., Tuber macrosporum, Tuber gibbosum, Tuber oregonense, and Tuber lyonii. The isolated pure truffle may then be cultivated on a nutrient substrate, which may be, for example, a fruit, nut, grain, or a portion thereof, resulting in a truffle-flavored food product. Non-limiting examples of such substrates include rye, barley, lentil, wheat, rice, soybeans, pecan, hazelnut, pine nut, English walnut, coffee beans, mustard, cacao, sesame, sunflower, grapes, blackberries, blueberries, cherries, kiwi, mango, raspberries, and huckleberries.

A method for culturing stem cells is used to solve the problem of loss of stem cell functionality after passaging. The method includes forming a mixed solution by adding an extract of Salvia miltiorrhiza into a basal medium. The stem cells are then cultured in the mixed solution. By the use of the extract of Salvia miltiorrhiza, division and differentiation capacities of the stem cells can be maintained even after passaging. The mixed solution for culturing the stem cells is also disclosed.

The present invention refers to a coating composition comprising a suspension of a microorganism, wherein the suspension comprises a pigmented vegetative cell, an unpigmented vegetative cell and a pigmented chlamydospore of the microorganism, and a surfactant ranging from 130 g/mol and 1500 g/mol. The invention further relates to a method for the preparation of the coating composition, a method for application coating one or more coating pre-layers and curing a material, a coated material obtainable by this method and a method for refreshing the coating of the coated material.

Artificial cervical fluid is disclosed that contains a mucilaginous extract from the okra plant. The mucilaginous extract can be produced using a hot aqueous extractant or cold extraction process followed by separation of larger particles from the extract. The extract finds many uses, for example as a sperm storage medium, a sperm freezing medium, a sexual lubricant, an artificial insemination medium, an in vitro fertilization medium, and methods for treating and/or preventing infection, replication, and transmission of viruses, such as sexually transmitted viruses.

According to the present disclosure, there is provided a system for culturing animal cells using a component derived from an organism such as algae as a nutrient source, and reusing the culture waste liquid. The present disclosure provides an organism or a cultured cell which undergoes a modification, in which the modification includes imparting or enhancing L-lactate utilization ability in the organism or the cultured cell. In addition, the present disclosure provides a method for culturing at least two types of cells including a cell X and a cell Y in a circulation manner, the method including: a step (a) of providing a component excreted from the cell X to the cell Y; a step (b) of providing a component derived from the cell Y to the cell X; a step (c) of culturing the cell X and the cell Y; and a step (d) of repeating the steps (a) to (c) as necessary, in which at least one of the components excreted from the cell X is an assimilable component of the cell Y, and at least one of the components derived from the cell Y is a nutritional component of the cell X.

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.

Methods and compositions related to thermogenic adipose for study and therapeutics are described. Certain embodiments are directed to vascularized thermogenic adipose tissue developed using microvascular fragments (MVFs). MVFs are isolated and thermogenic adipose formed.
