Seeding cells into needled felt scaffolds for tissue engineering applications SUMMARY: Tissue engineering methods are under development that will enable the repair or replacement of a variety of tissues‚ including articular cartilage and bone. To engineer functional tissue it is necessary that scaffolds initially be seeded with a large number of cells distributed evenly throughout the scaffold structure. It previously has been shown that‚ compared to static seeding conditions‚ seeding scaffolds

During WWII & the reign of Hitler was the Auschwitz Concentration Camp‚ a labor camp‚ which could be considered to be one of the worst places for a person of the Jewish faith place to be at that time in history. Handed down through history‚ it is considered to be one of the brutalist places on earth that a person could be. As James Deem described it‚ “Prisoners receiving punishment were often placed in cramped basement cells and deprived of food” (9). To be put into simple terms‚ it was torture.
