Abstract:
Compositions, peptide solutions and macroscopic scaffolds of self-assembling peptides consisting essentially of non-ionic, polar amino acids are provided. Particular peptides include those comprising, or consisting essentially of, serine, threonine, tyrosine, cysteine, glutamine, asparagine, methionine, tryptophan, hydroxy-proline, and combinations thereof. Methods of sterilizing the self-assembling peptides, and scaffolds comprising the peptides are also provided.
Abstract:
Materials and methods for bone void filling are provided. A peptide comprising between about 7 amino acids and about 32 amino acids in a solution may be introduced to a target site. The peptide may undergo self-organization under physiological conditions and/or in the presence of a cation.
Abstract:
Materials and methods for forming a bronchial obstruction are provided. A peptide comprising between about 7 amino acids and about 32 amino acids in a solution may be introduced to a target site. A hydrogel barrier may be provided at the target site in order to provide a bronchial obstruction.
Abstract:
Hemostatic powders are synergistically used in conjunction with self-assembling peptide hydrogels to promote hemostasis at a target site. Related methods, kits, and devices for hemostasis are disclosed.
Abstract:
Methods and materials for occluding a pancreatic fistula are described herein. One method for occluding a pancreatic fistula includes administering an effective amount of a self- assembling peptide solution to a pancreatic fistula, where the self-assembling peptide is between about 7 amino acids and 32 amino acids in length and the self-assembling peptide solution forms a hydrogel under physiological conditions, thereby occluding the pancreatic fistula.
Abstract:
Methods and materials for mitigating biological tissue adhesion are described herein. One method for mitigating adhesion to a biological tissue includes administering an effective amount of a self-assembling peptide solution to the biological tissue, wherein the self- assembling peptide is between about 7 amino acids and 32 amino acids in length and the self- assembling peptide solution forms a hydrogel under physiological conditions.
Abstract:
Synthetic peptide hydrogel solutions having a pH level of about 3.5 or less and a tonicity within an isotonic osmolality range for use in cell culture experimentation. Related kits and cell culture methods are also disclosed.
Abstract:
Provided are methods and compositions useful in the diagnosis, treatment, and monitoring of osteosarcoma. Antisense to certain microRNA (miRNA) found to be associated with cancer stem cells (CSCs) or tumor-initiating cells (TICs) of osteosarcoma are useful to suppress tumor growth and metastasis, and prolong survival. Antisense oligonucleotides to miR- 133a are synergistic in combination with standard chemotherapy such as cisplatin in the treatment of osteosarcoma.
Abstract:
Combination compositions comprising self-assembling peptides and payload agents, and methods of making and using such compositions, are described.
