Articular chondrocytes from patients with OA undergoing total knee replacement (Mankin Score > 3, Ahlbäck Score > 2) and from patients undergoing ACT, here referred to as normal donors (ND), were isolated applying protocols used for ACT.
To compare the status of these cells with cells that are actually used for ACT, chondrocytes obtained from human articular cartilage biopsies from the femoral notch of 41 patients undergoing ACT were included in this study.
We compared chondrocytes from osteoarthritis (OA) patients to chondrocytes from healthy donors directly after cell harvest (ex vivo) and to those from patients undergoing ACT after primary in vitro expansion (P0 cells) and first subculture (P1 cells).
All analyses were performed with cell samples from at least three separate donors unless otherwise indicated; as a comparison, surplus cells from three or four donors undergoing ACT were used [ 15].
NDs meet the demands of patients undergoing ACT treatment for isolated articular lesions without further indications such as OA or inflammatory diseases, in accordance with widely accepted treatment guidelines [ 52].
In a comparison between OA chondrocytes and those from patients undergoing ACT only one sample, from the affected side of a female aged 81 years, had a significantly lower content of proteoglycans (P < 0.05; Fig. 4a).
The donors age ranged from 60 to 64 years (average 62 years) with a Mankin score of 3 to 7. Control patients were selected for inclusion in the study if they had no pre-existing history of OA symptoms, macroscopically healthy cartilage, and were undergoing ACT treatment (these donors are referred to as normal donors (ND)).
John Varley's The Ophiuchi Hotline (1977) is an archive of methods to shatter old human verities: characters die and are reborn as clones, change sex with ease and alacrity, make backup tapes of their personalities, and undergo drastic acts of surgery all in a space-dwelling society that accepts such things as normal.
The treatment these celebrities received is portrayed as ineffective and ridiculous, suggesting celebrities should not have to undergo insincere acts of public apology for their sexual transgressions.
