From a cell population containing cardiomyocytes, the cardiomyocytes are extracted using a marker(s) specific to cardiomyocytes, that is, at least one marker selected from CORIN, NCAM1, CRYAB, HBEGF, DMD, ATPIF1, CAV2, ITGAV, DCBLD2, CLIC4, BMPR2, CTSB, TMEM123, USP14, and MIR761.

Amino acid residue misincorporations are necessarily found in sequence variants at low concentrations in admixture with expressed polypeptides, resulting from one or more base mismatches within codons susceptible to amino acid residue misincorporation during transcription and/or translation. The invention provides a method of optimizing the coding sequences of a polynucleotide that encodes a polypeptide, wherein at least one codon is susceptible to amino acid residue misincorporation. The method of the invention can be used to reverse-engineer an unknown coding sequence, which encodes the same polypeptide, but differs in said at least one codon from the known coding sequence. The method can further be used to alter the immunogenic potential of an expressed polypeptide. Thus, the invention is useful in engineering optimized polynucleotides encoding polypeptides.

Methods for preparing sequencing libraries from a DNA-containing test sample, as well as methods for correcting sequencing-derived errors, are provided.

This invention provides a system for efficiently producing differentiated cells from pluripotent cells, such as human embryonic stem cells. Rather than permitting the cells to form embryoid bodies according to established techniques, differentiation is effected directly in monolayer culture on a suitable solid surface. The cells are either plated directly onto a differentiation-promoting surface, or grown initially on the solid surface in the absence of feeder cells and then exchanged into a medium that assists in the differentiation process. The solid surface and the culture medium can be chosen to direct differentiation down a particular pathway, generating a cell population that is remarkably uniform. The methodology is well adapted to bulk production of committed precursor and terminally differentiated cells for use in drug screening or regenerative medicine.

The present disclosure relates to methods of collecting cervical-vaginal fluid exosomes and microvesicles and isolating corresponding mRNA. In particular, certain embodiments relate to the method of collecting the cervical-vaginal fluids with a tampon and releasing the cells, exosomes and microvesicles using excess buffer and a syringe or syringe-like device. The resulting expunged fluid can be applied to a filter device that is capable of capturing exosomes and microvesicles. Nucleic acids such as mRNA can be isolated from the cervical-vaginal fluid exosome and microvesicles using an oligo(dT)-coated plate designed to accommodate the filter device and then used for further molecular analysis. Quantification of the collected nucleic acids may then be used in the diagnosis and/or treatment of gynecological diseases or conditions.

The disclosure provides for screening methodologies using gene fragment overexpression that provide for the identification of peptide sequences which can modulate the functional regions of proteins of interests, and uses thereof. The disclosure further relates to peptide, polypeptide and polynucleotide identified by the methods of the disclosure, compositions containing such peptide, polypeptide and polynucleotides and uses thereof.

Provided are an RNA library construction method and a specialized kit thereof. The method for preparing an RNA library includes the following steps: extracting RNA and performing fragmentation; adding a tail to 3′ end; ligating an adaptor to 5′ end and hybridizing with a DNA probe mixture; the DNA probe mixture is composed of several DNA probes that are reverse complementary to an RNA that is expected to be removed; removing RNA from the hybrid and removing DNA; performing reverse transcription and PCR amplification to obtain a library solution. The present invention combines polyA tailing and 5′end ligation. The RNA content in the system can be quickly increased by polyA tailing, thereby avoiding subsequent purification losses.

The present invention is directed to compositions and methods for producing one or more polynucleotides from smaller oligonucleotide segments within an emulsion. In methods of the present invention, a support having one or more capture oligo-nucleotides is contacted with two or more corresponding tile oligonucleotides. Upon hybridization of the tile oligonucleotides to the capture oligonucleotides, a capture complex is formed. This capture complex is emulsified, optionally with reaction reagents or other additives. The emulsion is then incubated at a temperature regimen sufficient for an adjoining extension reaction to occur, such that a polynucleotide may be formed from the tile oligonucleotides that hybridized to a particular support. A particular advantage of this method is that many different polynucleotides may be produced in parallel with surprising efficiency.
