Abstract
Background Cell culture technology has spread prolifically within a century, a variety of culture media has been designed. This review goes through the history, characteristics and current issues of animal‐cell culture media. Methods A literature search was performed on PubMed and Google Scholar between 1880 and May 2016 using appropriate keywords. Results At the dawn of cell culture technology, the major components of media were naturally derived products such as serum. The field then gradually shifted to the use of chemical‐based synthetic media because naturally derived ingredients have their disadvantages such as large batch‐to‐batch variation. Today, industrially important cells can be cultured in synthetic media. Nevertheless, the combinations and concentrations of the components in these media remain to be optimized. In addition, serum‐containing media are still in general use in the field of basic research. In the fields of assisted reproductive technologies and regenerative medicine, some of the medium components are naturally derived in nearly all instances. Conclusions Further improvements of culture media are desirable, which will certainly contribute to a reduction in the experimental variation, enhance productivity among biopharmaceuticals, improve treatment outcomes of assisted reproductive technologies, and facilitate implementation and popularization of regenerative medicine.

Abstract
Amino acid transport was studied in freshly isolated adult rat hepatocytes using non-metabolizable alpha-amino-1-[14C] isobutyric acid and 1-aminocyclopentane-1-[14C] carboxylic acid. In the presence of sodium, hepatocytes concentrated alpha-aminoisobutyric acid; this concentrative component of the transport had properties similar to transport system A. The sodium-independent transport of aminocyclopentane carboxylic acid had properties similar to transport system L (facilitated diffusion). Glucagon stimulated the influx of alpha-aminoisobutyric acid into hepatocytes. The glucagon effect (a) occurred rapidly, but its full expression required two hours of exposure of the cells to hormone; (b) involved new protein (and possibly RNA) synthesis; and (c) occurred at low concentrations of glucagon (50% effect with 0.4 nm). Glucagon stimulated only system A. Cyclic AMP also stimulated the transport of alpha-aminoisobutyric acid. Freshly isolated hepatocytes appear conveniently suited to the investigation of various aspects of the regulation of liver amino acid transport in normal and pathophysiological states.

Abstract
The kinetics of controlled release of basic fibroblast growth factor (bFGF) from polymers (sutures, polycarbonate, Hydron, and Elvax), biopolymers (alginate), and biomatrices (lens capsules), and conditions for storage of bFGF (temperature, plastic type, heparin) were evaluated in vitro. Tissue culture proliferation bioassays with 3T3 fibroblasts, showed that only lens capsules with bFGF had a sustained release of bFGF for up to three weeks. The other materials released all of the 'bound' bFGF with two hours or produced an inflammatory response in vivo. Therefore, the lens tissue had the most potential for controlled long-term delivery of bFGF in vivo. These studies emphasise the importance of in vitro analysis of release kinetics of growth factors from a range of materials as a basis for potential in vivo applications.

Abstract
Neovascularization is associated with tumor growth and some inflammatory diseases but has not been reported to be induced by infectious agents. In a mouse model of systemic Candida albicans infection, extensive endothelial cell proliferation was seen in the periphery of brain abscesses and in the areas of fungal pyelonephritis in the kidney. This finding is important for an understanding of the pathogenesis of fungal infections and may contribute to an analysis of the mechanisms of angiogenesis.

Abstract
We have examined the effects of ciliary neurotrophic factor (CNTF) on the development of rat Purkinje cells in vitro. Cerebellar cells, derived from embryonic day 16 rat fetuses, were found to respond rapidly to CNTF treatment by induction of c-Fos protein, such that 40% of the cells were immunopositive after 60 min. Treatment with low doses of CNTF (10-100 pg/ml) for 8 days resulted in an approximately 1.6-fold increase in the number of Purkinje cells, identified by immunohistochemical staining for calbindin. Immunohistochemical staining for other Purkinje cell markers--cyclic-GMP-dependent protein kinase and the low-affinity nerve growth factor receptor--verified increased Purkinje cell survival following CNTF treatment. In addition, CNTF increased specific high-affinity GABA uptake by 45%, and the number of GABAergic neurons by 70%. A maximal increase in the number of Purkinje cells and GABA-uptake was only achieved if CNTF was added within 48 h of plating the cells, further suggesting that CNTF enhances Purkinje cell survival in vitro. These results taken together strongly support a direct effect of CNTF in promoting the survival of Purkinje cells and possibly other GABAergic cerebellar neurons.

Abstract
A compound that can enhance the apparent synthesis of acetylcholine in cultured explants of the medial septal nucleus has been purified from rat brain and identified as phosphoethanolamine. Acetylcholine synthesis is stimulated two- to threefold in cultures grown for 5 days in the presence of phosphoethanolamine, ethanolamine, or cytidine 5'-diphosphoethanolamine at concentrations above 100 microM. This effect appears to result from an increase in the accumulation of choline via the high-affinity, sodium-dependent uptake mechanism. The development of choline acetyltransferase activity is not affected. Phosphoethanolamine and ethanolamine seem to enhance the ability of developing cholinergic neurons to utilize choline accumulated via the sodium-dependent high-affinity choline uptake mechanism for the preferential production of acetylcholine without increasing the general metabolism of the cultures. Choline itself and its related derivatives are not stimulatory for these effects.

Abstract
The purpose of this study was to determine the proliferative activity of tissue repair fibroblasts recovered directly from injured peritoneum at various times after surgery and to test the mitogenic response of tissue repair cells (TRC) to growth factors. Rabbits underwent bilateral peritoneal abrasion (5 X 5 cm) with sterile gauze until punctate bleeding developed. Postsurgical (Days 2, 5, 7, and 10) tissue repair cells were recovered from the injured peritoneum by scraping with a scalpel blade. Although tissue repair cells consisted of a mixed cell type after 4 days in culture, recovered cells were essentially fibroblasts. These TRC were then pulsed with [3H]thymidine after 4 days in culture. The incorporation of thymidine into Postsurgical Day 5 TRC increased significantly compared to that of Day 2 TRC (P less than 0.05). Incorporation then decreased with time following surgery. Fibroblast growth factor (FGF) and epidermal growth factor (EGF) stimulated the incorporation of thymidine into TRC. However, the response of Postsurgical Day 7 and 10 TRCs to 1 microgram/ml EGF was significantly greater than those of Postsurgical Day 2 and 5 TRCs (Day 2 TRC, 166 +/- 7.4; Day 10 TRC, 420 +/- 96% of control cells without EGF, P less than 0.05). Platelet-derived growth factor (PDGF, 10 ng/ml) also stimulated the incorporation of thymidine into Day 10 TRCs, but this stimulatory activity (129.9 +/- 8.5% of control) was less than EGF or FGF. IL-1 alpha and IL-2 did not stimulate the incorporation of thymidine into TRC at a concentration of 100 pg/ml, but these cytokines did stimulate protein synthesis by TRC.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Macrophages and fibroblasts are major components of the postsurgical repair process. In order to understand more fully the interaction between these two cell types, we studied the modulation by macrophages of the incorporation of [3H]thymidine into postsurgical fibroblasts recovered from the site of peritoneal injury. Peritoneal exudate cells (PEC):(greater than 95% macrophages) were collected from rabbits 4 and 7 days after resection and reanastomosis of the small intestine. PEC were suspended in Medium 199 (M-199) with 3% fetal calf serum (FCS) and incubated for 48 hr. Fibroblasts were obtained from rabbits that underwent abrasion of the parietal peritoneum 7 days previously, and were cultured for 7 days in M-199 with 3% FCS. Fibroblasts were then replated and incubated with macrophage-spent medium. Incorporation of [3H]thymidine into fibroblasts was significantly suppressed after 24 hr of incubation with macrophage-spent media compared to the incorporation by fibroblasts incubated with fresh medium (control). This suppression was most profound when fibroblasts were incubated with resident (nonsurgical) macrophage-spent medium. The incorporation of thymidine by macrophage-spent media groups then increased rapidly and reached control levels at 48 hr of incubation. After 54 hr of incubation, the incorporation of thymidine by fibroblasts incubated with media from postsurgical macrophages was significantly higher than that of control. Morphological changes in fibroblasts also appeared as the culture with macrophage-spent media progressed. Initially, fibroblasts were shaped like pine needles, but after 7 days of culture, fibroblasts assumed a spherical shape. Round-shaped fibroblasts returned to the original morphology (pine needle shape) after incubation for 48 hr with macrophage-spent medium.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Macrophages and fibroblasts are major components of postsurgical peritoneal repair. In order to understand the interaction between these two cell types, we studied the effects of spent macrophage culture media on fibroblast proliferation. Rabbits underwent resection and reanastomosis of their small intestine. Peritoneal exudative cells (PEC) were then collected from these animals on postoperative Days 4, 7, and 28 and from nonsurgical controls. PEC (5 X 10(5) cells/ml) were cultured in M-199 with 3% fetal calf serum. After 48 hr the spent media from the cultured PEC were harvested, centrifuged (200g for 10 min), and stored (medium: M-D0, D4, D7, D28). A second group of rabbits underwent peritoneal wall abrasion followed by collection of fibroblasts directly from the site of injury on postoperative Days 1, 4, and 7. After Day 7 of culture, fibroblasts were resuspended and seeded into dishes (1 X 10(5) cells in 1 ml medium), to which was added 1 ml of spent PEC culture medium. After 24 hr of incubation, 1 muCi [3H]thymidine was added for an additional 18 hr. Fibroblasts were then collected and the amount of [3H]thymidine incorporated into trichloroacetic acid-precipitable material was quantitated. In one protocol, fresh M-199 with 3% fetal calf serum was used, and in another protocol, "U-medium" (which was previously incubated for 48 hr with fibroblasts) was used. The cytology of the PEC was determined by Wright's staining, nonspecific esterase activity, and phagocytosis. At least 80% of the peritoneal exudative cells were identified as macrophages. Postsurgical Day 7 fibroblasts demonstrated greater [3H]thymidine incorporation compared to fibroblasts from postoperative Days 1 and 4.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Serum is reported to reduce the sensitivity of cells in culture to insulin. The effect of serum concentration in the growth medium on the responsiveness of control (C) and streptozotocin diabetic (D) rat gingival fibroblasts to insulin was measured by monitoring cellular DNA, RNA, total protein and medium hydroxyproline (collagen) levels, as well as the cellular uptake of C14-alpha-NH2-isobutyrate (alpha-AIB) and H3-2-deoxyglucose (2DG). The cells were grown in alpha-MEM at 5, 10, 15 or 20% FCS with 0, 10(-12), 10(-10), 10(-8) and 10(-6) M insulin used at each serum level. Insulin effects in the absence of serum were not assessed. For both the C and D rat cells, the DNA increased proportionately with increasing serum and insulin levels. In contrast, RNA and total cell protein increased with increase in insulin and decrease in serum, the magnitude of the effect being greater in C than in D cells. The insulin stimulation of both 2DG and alpha-AIB uptake and of collagen secretion varied inversely with serum concentrations. The magnitude of the insulin-serum interaction on metabolite uptake was greater for the D rat cells. These data indicate that serum significantly reduced the cell response to insulin stimulated metabolite uptake and collagen secretion, but was without apparent effect on the intracellular insulin responsive parameters. They suggest that serum factor(s) interfere with the availability of insulin to the cell and that the D rat cells are most affected.

Abstract
We studied the modulation of fibroblast proliferation and transformation by postoperative macrophages. One group of rabbits underwent resection and reanastomosis of the small bowel, after which macrophages were collected by peritoneal lavage. A second group of rabbits underwent peritoneal wall abrasion followed by collection of local fibroblast on postoperative days 4 and 8. Postoperative macrophages were added to five culture dishes containing fibroblasts. After 24 hours, tritiated thymidine was added to the culture dishes and incubated overnight. In two other dishes, which were incubated for up to 8 days, a 24-hour pulse of tritiated thymidine was added before culture termination. Postoperative day 4 fibroblasts demonstrated a greater increase in cell number during the culture interval compared to fibroblasts collected on postoperative day 8. By the second day of coculture with macrophages collected from different postoperative days, tritiated thymidine incorporation by day 4 fibroblasts was suppressed, especially by postoperative day 7 macrophages. Thereafter, a stimulation in tritiated thymidine uptake was found. In contrast, tritiated thymidine uptake by day 8 fibroblasts was accelerated by coculture with macrophages, especially those collected on postoperative day 7. Day 4 fibroblasts assumed a more spindly appearance when cocultured with macrophages than did day 8 fibroblasts. Taken together, these data suggest that macrophages activated in response to surgical injury may secrete substances that induce proliferation and transformation of fibroblasts.

Abstract
Primary mass cultures and cloned strains of bovine aortic endothelial and smooth muscle cells were investigated with respect to their growth responses to glucocorticoid hormones. The growth of primary endothelial cells was not influenced by glucocorticoid treatment in the absence of fibroblast growth factor (FGF) but was inhibited by about 30% in the presence of FGF; with cloned endothelial cells, glucocorticoids were also growth inhibitory only in the presence of FGF. In contrast, smooth muscle cell growth was inhibited 30%-70% by glucocorticoid treatment in both primary cultures and in the cloned strains in the absence of FGF, and this inhibition was totally abolished by the addition of FGF for both cultures. The corticosteroid influences on cell growth were glucocorticoid specific, concentration dependent, and were observed to be independent of the serum concentration. The results indicate that glucocorticoid hormones have direct and pronounced growth inhibiting effects on aortic smooth muscle cells but only minimal effects on endothelial cells when these components of the vascular wall are analyzed under identical conditions in vitro.

Abstract
Activities of cyclic-nucleotide-hydrolysing enzymes cAMP-, cCMP- and cGMP phosphodiesterase, the intracellular concentrations of cAMP, cCMP, and cGMP, and the activity of the cAMP-dependent protein kinase were studied in serum-starved 3T3 cells stimulated to proliferate by serum. Within 1 and 2 min after stimulation the activities of cAMP- and cGMP phosphodiesterase were unaffected while the concentration of cGMP was raised and that of cAMP lowered, suggesting increased synthesis of cGMP and simultaneously reduced synthesis of cAMP. 48 h after stimulation, when the cells multiplied rapidly, both the cAMP phosphodiesterase and the cCMP phosphodiesterase were reduced. Evidence was also obtained that cAMP-dependent protein kinase is important for expressing the cAMP effect in the 3T3 cells.

Abstract
Improved culture conditions have been developed that will support clonal growth of Swiss mouse embryo 3T3 cells at concentrations of serum protein at low as 125 micrograms/ml. Survival of the cells under completely protein-free conditions also is enhanced greatly. The improvements that made these results possible include: (a) use of medium MCDB 402, which was developed specifically for Swiss 3T3 cells by adjusting the concentrations of all components of Dulbecco's modified Eagle's medium to optimum values for clonal growth with minimal serum protein and by adding other nutrients such as trace elements and "nonessential" amino acids that were not in the original formula; (b) use of culture surfaces that are coated with a positively charged polymer, poly-D-lysine; and (c) use of gentle low temperature trypsinization technique that minimizes cellular damage and the need to neutralize residual trypsin.

Abstract
The glucose analogues, 3-O-methyl-D-glucose and 2-deoxy-D-glucose, have been used to characterize glucose transport and its regulation by serum and growth factors in monolayer cultures of granulosa cells obtained from bovine ovaries. Uptake of 3-O-methylglucose was shown to be independent of the Na+-gradient, independent of energy, did not show accelerated exchange, and was stereospecific. Serum withdrawal resulted in a biphasic decrease in initial rates of glucose uptake with half-times for the two phases of 50 minutes and 3 hours. Insulin could prevent the decrease in uptake rates with a half-maximum concentration of 10.0 1/8 3 nM. Insulin was shown to stimulate DNA synthesis with a concentration of half-maximum response of 28 nM. Insulin or serum stimulation of 3-O-methylglucose uptakes in serum-starved cells resulted in a two threefold increase in initial rates, with a time for half-maximum stimulation of 3 minutes. The insulin-stimulated increase was insensitive to cycloheximide and cyanide during the first 30 minutes, and this early, rapid stimulation was also produced by brain FGF (fibroblast growth factor), pituitary FGF, epidermal growth factor, calf serum, and some but not all samples of follicular fluid. Insulin also stimulated 2-deoxyglucose and a-aminoisobutyric acid uptake during the first 5 minutes of addition and these early stimulations were shown to be posttranslational changes.

Abstract
Components of the renin-angiotensin system were studied in established cell culture lines of 3T3 and SV3T3 mouse fibroblasts. The renin content in 3T3 cells was significantly higher than in virus-transformed SV3T3 cells. With time after infection, renin decreased in Simian virus 40 transformed cells, while it increased steadily in mock-infected 3T3 cells. In contrast to renin, angiotensinase activity was higher in SV3T3 cells. Angiotensin II stimulated cell proliferation in 3T3 mouse fibroblasts and decreased their renin content in a dose-related manner. In contrast, saralasin, an angiotensin receptor antagonist, inhibited cell growth in 3T3 and SV3T3 cells and caused an increase of cellular renin concentration. The angiotensin fragments angiotensin (2-8) heptapeptide and angiotensin (4-8) pentapeptide had no effect on cell growth. A significant negative correlation was found between cell proliferation and renin levels in 3T3 and SV3T3 cells irrespective of the treatment. Our results indicate (1) that angiotensin II may be involved in cell growth regulation, (2) that a negative feedback exist between angiotensin II added and intracellular renin content, and (3) that virus infection causes a decrease in intracellular renin synthesis, while non-specific angiotensinase activity is increased under this condition.

Abstract
An explanation of organismic ageing based on a limited division capacity of dividing cells is difficult to reconcile with much of the available data. The physiology of cells in ageing organisms tends, on the contrary, to suggest that organisms age as a result of degeneration in their non-dividing cell populations. Senescence in these non-mitotic cells resmebles the ageing of the non-dividing fraction of cell cultures clonally senescing, or maintained in long-term quiescence in vitro. As cultures of diploid human fibroblasts senesce there is an accumulation of non-dividing cells. Alterations in these post-mitotic cells can explain the senescent properties of late passage cultures. It is proposed that during the in vitro senescence of fibroblast cultures, cell ageing results from, as opposed to causes, the absence of mitosis. Cell ageing may primarily result from changes in the chromatin induced by the non-mitotic state.

Abstract
Monkey fibroblasts maintained in culture regulate their levels of intracellular protein throughout the growth cycle by means of variations in the rate of protein biosynthesis. Cytoplasmic mRNA in stationary phase cells was compared to that in exponential phase cells. In stationary phase cells 56% of the cytoplasmic polyadenylated RNA was found in the 40--90S postpolysomal region of sucrose sedimentation gradients, while only 23% was found in this region in exponential phase cells. Analysis of electron micrographs of sectioned exponential and stationary phase cells revealed that this shift in polyadenylated RNA location is accompanied by a loss of polysome-like aggregates of ribosomes. Most if not all of this species of postpolysomal polyadenylated RNA is not being translated by single ribosomes since no detectable amounts of nascent peptide were present in this region. This nonpolysomal polyadenylated RNA is comparable in size to polysomal polyadenylated RNA. The length of the 3'-poly(A) tract was also comparable for these two species. The extent of capping of poly(A)-containing molecules was also comparable for these two species. The template activity of nonpolysomal RNA in a wheat germ extract was comparable to that of polysomal RNA. The peptides produced by these two preparations were of a similar large size. Furthermore, most of the nonpolysomal polyadenylated RNA of stationary phase cells was driven into polysomes in the presence of a low dose of cycloheximide. Therefore, we conclude that the untranslated mRNA that accumulates in stationary phase cells is structurally intact, is fully capable of being translated, and is not being translated due to the operation of a translational initiation block.

Abstract
This study involves the use of fibroblast growth factor (FGF) as a substitute for exogenous serum to examine the early transport changes which occur when quiescent 3T3 cells re-initiate active growth. FGF, in nanogram amounts, together with insulin and dexamethasone, can induce mitogenesis and mitosis in 3T3 cells GO-arrested by holding in growth medium containing 0.8% calf serum. In terms of quiescent cell transport activity enhancement, FGF is 300,000-fold more effective than fresh serum, on a protein basis. In addition, very short exposure of serum-depleted cells to FGF indicates that a distinct temporal or time sequence exists in the transport system activation process. For example, uptake of alpha-aminoisobutyric acid (AIB) and uridine are stimulated very rapidly, whereas hypoxanthine uptake does not respond until much later. Closer analysis shows that AIB uptake is maximally enhanced within zero to two minutes after FGF addition to cells. Finally, the stimulatory effect of FGF on transport system activities is specific in terms of the proliferative state of the cells to which it is added, and in terms of the uptake systems which respond to it.

Abstract
The effects of fibroblast and epidermal growth factors on proliferation and differentiation of cultured myoblasts and chondrocytes have been compared. FGF stimulated myoblast proliferation, as determined by monitoring levels of DNA synthesis during seven days growth in vitro and by the morphology of the cultures after myotube formation. EGF has relatively little effect on myoblast proliferation. With chondrocytes, both FGF and EGF are mitogenic and FGF's, but not EGF's effect is potentiated by dexamethasone. One implication of these results is that in the course of differentiation cell types which develop from the same embryonic origin as fibroblasts are controlled by different sets of mitogenic factors. Myoblasts become primarily dependent on mitogenic agents such as FGF while chondrocytes can respond to both FGF and EGF.

Abstract
A group of enzymes known to be involved in group translocation-type transport mechanisms for the uptake of a variety of nucleotide precursors are enzymatically active both in their natural membrane milieu and in aqueous solution. The activity in aqueous solution markedly differ, however, from the enzymatic activity when the enzyme is membrane localized. The adenine phosphoribosyltransferase (PRT) of E. coli (Hochstadt-Ozer and Stadtman, 71a) is capable of carrying out an exchange reaction between the base moieties of adenine and AMP without requiring P-ribose-PP as an intermediate; the enzyme in aqueous solution requires P-ribose-PP, indicating a different reaction mechanism in the two environments. Like the adenine PRT of E. coli, the hypoxanthine PRT of Salmonella typhimurium (Jackman and Hochstadt, '76) also carried out an exchange reaction on the membrane only and also is more sensitive to a number of inhibitors in aqueous solution relative to the sensitivity when embedded in the membrane. In addition, however, the hypoxanthine PRT, while restricted to hypoxanthine as a substrate in the membrane, also accepts guanine as substrate in its soluble form. The membrane capacities reas determined in a guanine PRT deletion strain (Jackman and Hochstadt, '76). Finally, in mammalian cell lines purine nucleoside phosphorylase, which translocates the ribose moiety of inosine across the plasma membrane of mouse fibroblasts undergoes a 30-fold increase in substrate turnover number upon liberation from the membrane. These data raise two important caveats with respect to study of membrane enzymes and transport. Firstly, an enzyme once solubilized and found to differ kinetically from substrate transport in situ cannot be excluded from participating in translocations in the membrane on the basis of its activity in aqueous solution. Secondly, an enzyme which "appears" largely soluble upon cell rupture cannot be assumed to be a cycloplasmic enzyme because of majority of the solubilized activity may represent only a small fraction of the enzyme molecules highly activated concomitant to their solubilization. In this latter case the ability to activate enzyme still residing on the membrane (e.g., with detergents) would be necessary in order to estimate total membrane associated activity after cell rupture.

Abstract
The effect of fibroblast growth factor (FGF) on the rate of proliferation and fusion of bovine myoblast has been examined. Addition to the cultures of 0.1 mug-1 mug/ml of FGF stimulates the rate of proliferation and delays the fusion of primary cultures of bovine myoblasts cultured in 10% serum. Final cell densities reached in the presence of 0.1 mug/ml of FGF were fivefold higher than in controls; with 1 mug/ml, they were 10-fold higher. Increases in cell density were paralleled by increases in acetylcholine receptor sites as measured by the binding of 125I-alpha-bungarotoxin. Both fusion and the appearance of acetylcholine receptor sites were delayed in the presence of FGF. Growth hormone, insulin and testosterone, which have been reported to be mitogenic for rat and chick embryo myoblasts, did not have significant effects on DNA synthesis in bovine myoblasts when compared to the FGF. Conversely, FGF did not stimulate the proliferation of chick embryo myoblasts, indicating that it is not active in all vertebrate species.

Abstract
The Balb/3T3 and C3H/10T1/2 lines, noted for their marked postconfluence inhibition of proliferation and anchorage dependence, and frequently studied as non-tumorigenic lines that are compared with tumorigenic sublines transformed with various agents, produced tumors within two to four months at low-cell dosage (3 X 10(4) cells) when implanted subcutaneously attached to 1 X 5 X 10 mm polycarbonate platelets. Platelets alone did not produce tumors. The cultured Balb/3T3 tumor cells showed loss of both postconfluence inhibition of proliferation and anchorage dependence. Tumors arising from attached Balb/3T3 cells in (BALB/c X C57B1/6)F1 hybrids were shown to be transplantable to BALB/c but not to C57B1/6 mice, proving that the tumors were derived from Balb/3T3 and not from host cells. The tumors exhibited unique transplantation rejection antigens that did not cross-react with each other. Scanning electronmicroscopy of Balb/3T3 cells and derived tumor cells on Teflon substrates (on which only the tumor cells and not the parent Balb/3T3 cells could grow) revealed that the two cell types were remarkably similar in appearance, except that the tumor cells were larger and showed many more microvilli that tended to concentrate over the nucleus. We conclude that Balb/3T3 cells and C3H/10T1/2 cells are preneoplastic and give rise to spontaneously transformed clones when implanted in vivo attached to a solid substrate.

Abstract
Fibroblast growth factor (FGF), a polypeptide that has been shown to stimulate division in 3T3 cells, was tested for mitogenic effects on diploid, early-passage cells from human and murine sources. The quantitative assay of [3H]thymidine incorporation into acid-insoluble material showed that FGF at low concentrations (10 minus 9 M) was more effective than additional serum for provoking the initiation of DNA synthesis in human foreskin fibroblasts or mouse fibroblasts maintained in 5 or 10% serum, respectively. The growth of the human fibroblasts was twice as fast in the presence of FGF plus 10% calf serum as it was in the presence of 10% calf serum or 20% fetal calf serum alone. The addition of FGF to primary cultures of mouse fibroblasts in 0.4% serum resulted in a twofold increase in cell number compared to controls. In contrast to results obtained with 3T3 cells, neither insulin nor a glucocorticoid potentiated the effects of FGF on either human or mouse cells.
