Described herein are aptamers that bind to the transferrin receptor (e.g., CD71) and can be used, in part, for depleting transferrin receptor-expressing cells from a population of therapeutic cells. These aptamer compositions can be used in methods for isolating and/or enriching cells expressing CD71 or depleting cell populations of cells expressing CD71, including for example, tumor cells. Further provided are methods of using the aptamers or cell populations generated using them in the methods disclosed herein for therapies and/or drug delivery.

The present invention relates to non-elicited dedifferentiated plant cells of a plant of the species Lavandula angustifolia, or extracts thereof, and also to the cosmetic composition comprising same, to the uses thereof and to cosmetic treatment processes comprising the application of said composition to the skin for improving and/or reinforcing the barrier function, and also for improving the moisturization of the skin.

A scaffold with hierarchical structure, a preparation method therefor and an application thereof. The scaffold with hierarchical structure has a structure ranging from centimeters to micrometers, and is used in the fields of three-dimensional cell culture, in vitro large-scale amplification, in vitro tissue-like construction, tissue engineering and regenerative medicine, pathological model research, new drug research and development, drug toxicology research and the like.

Disclosed herein are antibodies that specifically bind and inhibit the action of the IL-6 family member LIF that are useful in the treatment of cancer. Also disclosed herein are uses of said antibodies for the treatment of cancer.

The present invention relates to RNA-free mammal serums which can be useful for cell culture or for producing pharmaco-biological products, due to the fact that they maintain their supplement features. Another embodiment of the invention refers to the method for removing RNA from mammal serum through the application of sequential serum heating, alkalisation and neutralisation steps.

Disclosures herein are directed to chemically defined animal-derived component free supplements designed for individual cell types that supports the ex vivo growth of cells as well or better than serum, in chemically defined conditions.

Described herein are bioprinters comprising: one or more printer heads, wherein a printer head comprises a means for receiving and holding at least one cartridge, and wherein said cartridge comprises contents selected from one or more of: bio-ink and support material; a means for calibrating the position of at least one cartridge; and a means for dispensing the contents of at least one cartridge. Further described herein are methods for fabricating a tissue construct, comprising: a computer module receiving input of a visual representation of a desired tissue construct; a computer module generating a series of commands, wherein the commands are based on the visual representation and are readable by a bioprinter; a computer module providing the series of commands to a bioprinter; and the bioprinter depositing bio-ink and support material according to the commands to form a construct with a defined geometry.

The present invention provides a composite which can be produced by photostructuring a photostructurable matrix material in a composite formulation to form a structured matrix with nanoparticles, where the refractive index of the composite with nanoparticles differs from the refractive index of the composite without nanoparticles at one wavelength, selected from the range from 150 nm to 2000 nm by less than 0.5, said composite being hierarchically structured and comprising at least one structural unit (I) of a selected thickness (i) and structural units (II) branching from said structural unit (I) of a selected thickness (ii), wherein the thickness (ii) at the branch-off points is at most half the thickness (i). In addition, the present invention provides an improved process for the preparation of a composite comprising photostructured matrix material and nanoparticles contained therein and the use of the composite.
