US Patent:

6528245, Mar 4, 2003

Filed:

May 7, 1999

Appl. No.:

09/307824

Inventors:

Juan Sanchez-Ramos - Tampa FL
Shijie Song - Tampa FL
William Janssen - Tampa FL
Paul Sanberg - Spring Hill FL
Thomas Freeman - Tampa FL

Assignee:

University of South Florida - Tampa FL

International Classification:

A01N 102

US Classification:

435 11, 435368, 435325

Abstract:

Bone marrow stromal cells (BMSC) differentiate into neuron-like phenotypes in vitro and in vivo, engrafted into normal or denervated rat striatum. The BMSC did not remain localized to the site of the graft, but migrated throughout the brain and integrated into specific brain regions in various architectonic patterns. The most orderly integration of BMSC was in the laminar distribution of cerebellar Purkinje cells, where the BMSC-derived cells took on the Purkinje phenotype. The BMSC exhibited site-dependent differentiation and expressed several neuronal markers including neuron-specific nuclear protein, tyrosine hydroxylase and calbindin. BMSC can be used to target specific brain nuclei in strategies of neural repair and gene therapy.

International Classification:

C12N 5/08

US Classification:

435368, 435325, 435366, 435383

Abstract:

The subject invention pertains to materials and methods for inhibiting process formation and extension by cells in culture. The subject invention further includes cultures of process-forming cells wherein formation and extension of processes have been inhibited. In another aspect, the subject invention concerns methods of transplantation using process-forming cells that have been cultured by the process-inhibiting methods of the invention.

International Classification:

C12N 5/00

US Classification:

435325

Abstract:

The subject invention pertains to tumor cell lines useful for increasing the proliferation potential of any human or animal cell in culture, thereby providing immortalized or continuous cell lines and cultures. The invention also concerns proliferation factors, and compositions containing the factors, which are capable of increasing the proliferation potential of any human or other animal cell in culture. The subject invention further pertains to a method for proliferation cells in culture by contacting cells with the proliferation factors. The proliferated cells can range in plasticity and can include, for example, blast cells, fertilized ova, non-fertilized gametes, embryonic stem cells, adult stem cells, precursor or progenitor cells, and highly specialized cells. Optionally, the cells can be induced to cease proliferation. The proliferation cells of the subject invention are useful for cell therapy, cell/gene therapy, biological production of molecules, and as in vitro models for research, toxicity testing, and drug development.

Filed:

Apr 18, 2007

Appl. No.:

11/736627

Inventors:

Thomas B. Freeman - Tampa FL, US
Wesley Johnson - Tampa FL, US

Assignee:

University of South Florida - Tampa FL

International Classification:

A61B 17/80

US Classification:

606286, 606280, 606287

Abstract:

An anti-subsidence, anti-translocation, fusion compression cervical plate system with interface visualization, drill guide and temporary pin is provided. In one embodiment the invention provides a vertebral plate for minimizing the ability of an inter-body cage, filled with bone (or BMP-soaked sponges, etc. ), to telescope into the vertebral body and to minimize failure due to cages that telescope into adjacent vertebral bodies on a delayed basis after surgery, as well as creation of reverse lordosis due to such telescoping. Another embodiment provides method to reduce the gap between the inter-body cage and the vertebral body end plate intra-operatively using compression from the plate caused by an offset between the screw bores on the plate and the drill holes, as established with an asymmetric drill guide.

Appl. No.:

10/908648

Inventors:

Thomas B. Freeman - Tampa FL, US
James P. O'Connor - Billerica MA, US

Assignee:

University of South Florida - Tampa FL

International Classification:

A61B 19/00

US Classification:

606130

Abstract:

The present invention makes a grid array, for use in the transplantation of materials into the brain, in the shape of a predetermined structure, such as the putamen, based on anatomic analysis the structure. Alternatively, a smaller grid array is used which only includes the putamen target and not the caudate target, and also has two windows within the grid array. Because of the smaller size of this grid array as well as the two cutouts in the middle, it is possible for the first time to observe the brain as the needle enters the brain through the grid array. The previous solid and larger grid array made the passage of the needle into the brain a blind maneuver. Therefore if there was cortical bleeding at the time of needle insertion, it would not be known until after the transplant was done.

International Classification:

A61F 2/44

US Classification:

623 1711, 623 1712

Abstract:

The present invention provides both a device and a method. The device is a human made replacement for the soft discs in the spine. A fabric pouch encloses a central hydraulic element made up of small soft beads. Two pouches with beads are implanted into a prepared disc space to function as an intervertebral disc. The method is conversion of the device into a fusion element.
