The first object of the present invention is to provide an immortalized cell line derived from a thread-sail filefish. The first object of the present invention can be solved by a cell line or a passage strain thereof derived from a living body part of a fish of the family Monacanthidae, wherein the cell line or the passage strain thereof is capable of being subcultured substantially without limitations. The second object of the present invention is to provide a pluripotent stem cell derived from a thread-sail filefish. The second object of the present invention can be solved by a cell line or a passage strain thereof derived from a living body part of a fish of the family Monacanthidae, wherein the cell line or the passage strain thereof is positive for at least a cell marker selected from a group consisting of TRA-1-60, OCT4 and SSEA-3.

The invention relates to an approach for introducing one or more desired insertions and/or deletions of known sizes into one or more predefined locations in a nucleic acid (e.g., in a cell or organism genome). They developed techniques to do this either in a sequential fashion or by inserting a discrete DNA fragment of defined size into the genome precisely in a predefined location or carrying out a discrete deletion of a defined size at a precise location. The technique is based on the observation that DNA single-stranded breaks are preferentially repaired through the HDR pathway, and this reduces the chances of indels (e.g., produced by NHEJ) in the present invention and thus is more efficient than prior art techniques. The invention also provides sequential insertion and/or deletions using single- or double-stranded DNA cutting.

The present disclosure provides a modified cell of leukemic origin comprising a downregulated CD47 pathway. Methods for using the modified cells in treating cancer alone, or in combination with CD47 blockade are also provided. Also provided are compositions comprising a modified cell of leukemic origin, pharmaceutical compositions and formulations thereof, and methods of producing the modified cells.

The present invention describes transgenic animals with human(ized) immunoglobulin loci and transgenes encoding human(ized) Igα and/or Igβ sequences. Of particular interest are animals with transgenic heavy and light chain immunoglobulin loci capable of producing a diversified human(ized) antibody repertoire that have their endogenous production of Ig and/or endogenous Igα and/or Igβ sequences suppressed. Simultaneous expression of human(ized) immunoglobulin and human(ized) Igα and/or Igβ results in normal B-cell development, affinity maturation and efficient expression of human(ized) antibodies.

Provided herein are compositions and methods for producing immortalized, cystogenic, single cyst-derived cells from a polycystic kidney. Populations of immortalized, cystogenic, single cyst-derived cells from a polycystic kidney are also provided.

Therapeutics and methods for treating a stroke in a human comprising administering a therapeutic to the patient, wherein the therapeutic comprises one of immortalized human placenta mesenchymal stem cells (hPMSCs) and a product from the immortalized hPMSCs. Methods and therapeutic products comprising extracellular vesicles (EVs) isolated from of immortalized hPMSCs. Therapeutics and methods of treating COVID-19 disease vascular injury comprising administering a therapeutic to the patient, wherein the therapeutic comprises one of hPMSCs and a product from the hPMSCs.

The current disclosure provides methods and compositions useful in preparing transformed and immortalized zebra and quagga mussel cells that function as disseminated neoplastic (DN) cells, as well as the cells produced thereby. Also provided are methods for using such mussel DNCs in cell culture, in vitro, and within live mussels in the lab or in the wild, to control mussel populations such as invasive zebra mussel or quagga mussel populations.

The present disclosure is directed to methods for the formation and production of renewable muscle and/or fat primary cell lines, immortalized cell lines, and stem cell lines from shrimp, prawn, crab, crayfish, and/or lobster species and the cell lines themselves as well as human and animal consumable meat products produced therefrom.

The invention relates to induced pluripotent stem cells that are generated from cells, for example Adult Stem Cells, that are conditionally-immortalisable. In particular, the invention relates to induced pluripotent stem cells generated from stem cell lines comprising a controllable transgene for conditional immortalisation, and the progeny of those induced pluripotent stem cells. Induced pluripotent stem cells, progeny cells derived from those pluripotent cells, compositions comprising those cells, methods of making all of those cells, and uses of all of those cells are also described.

The invention provides a cell-containing vessel comprising a plurality of neural cell-containing spheroids for which the variation calculated using the calculation method described below is less than 20%, wherein the neural cell-containing spheroids contain a plurality of types of cells including neural cells,

(Calculation Method)

Calcium transient assays are conducted for each of a plurality of neural cell-containing spheroids, a number of spontaneous oscillations in a 10-minute period is measured, an average and standard deviation for the number of spontaneous oscillations are calculated, and a variation is calculated using formula (1) below:

Variation (%)=standard deviation for number of spontaneous oscillations/average number of spontaneous oscillations×100  (1).
